Chemical & Petroleum, Civil & Environmental, Electrical & Computer, MEMS, Diversity

PITTSBURGH (August 23, 2019) … Five faculty members from the University of Pittsburgh’s Swanson School of Engineering have been named CAREER Award recipients by the National Science Foundation (NSF). Recognized as the NSF’s most competitive award for junior faculty, the grants total nearly $3 million in funding both for research and community engagement. The CAREER program “recognizes faculty who exemplify the role of teacher-scholars through outstanding research, excellent education and the integration of education and research within the context of the mission of their organizations.” The five awards – one each in the departments of Bioengineering, Chemical and Petroleum, Civil and Environmental, Electrical and Computer, and Mechanical Engineering and Materials Science – ties the record from 2017 for the most received by Pitt and Swanson School faculty in a single NSF CAREER funding announcement. “Federal funding for academic research is extremely competitive, especially for faculty just beginning their academic careers. Receiving five prestigious NSF CAREER Awards in one cycle is a reflection of our winners’ distinctive research and support by their respective departments and the Swanson School,” noted David Vorp, PhD, the Swanson School’s Associate Dean for Research. He added, “Since a CAREER Award is also focused on community engagement, this is an opportunity for our faculty and their graduate students to promote STEM to children in the area, especially in underserved populations, and we will be working with them to develop impactful outreach programs.”Dr. Vorp also noted that the Swanson School’s recent success with CAREER awards can be attributed to a number of factors, including the School’s Center for Faculty Excellence, directed by Prof. Anne Robertson, and the CAREER writing group developed and run by Julie Myers-Irvin, PhD, the Swanson School’s Grants Developer. “Participating faculty acknowledge that the writing group focus on early preparation, group comradery, technical feedback, and discussions of grantsmanship practices attribute to more well-rounded proposals,” Dr. Myers-Irvin says.The award recipients include:Murat Akcakaya, Assistant Professor of Electrical & Computer Engineering, with Carla A. Mazefsky, Associate Professor of Psychiatry and Psychology ($550,000)Title:Toward a Biologically Informed Intervention for Emotionally Dysregulated Adolescents and Adults with Autism Spectrum Disorder (#1844885)Summary: Although clinical techniques are used to help patients with Autism Spectrum Disorder (ASD) respond to stress and other factors, none are known to couple with technology that could monitor brain response in real time and provide the patient with feedback. Drs. Akcakaya and Mazefsky are developing a new intervention using electroencephalography (EEG)-guided, non-invasive brain-computer interface (BCI) technology could complement clinical treatments and improve emotion regulation in people with ASD.Dr. Akcakaya will also develop courses related to the research and outreach activities to promote STEM and ASD research to K-12 populations and the broader public. Outreach will focus especially on individuals with ASD, their families, and caretakers. Susan Fullerton, Assistant Professor of Chemical and Petroleum Engineering ($540,000)Title:Scaling Electrolytes to a Single Monolayer for Low-Power Ion-Gated Electronics with Unconventional Characteristics (#1847808)Summary: Two-dimensional (2D) materials are being explored for their exciting new physics that can impart novel functionalities in application spaces such as information storage, neuromorphic computing, and hardware security. Dr. Fullerton and her group invented a new type of ion-containing material, or electrolyte, which is only a single molecule thick. This “monolayer electrolyte” will ultimately introduce new functions that can be used by the electronic materials community to explore the fundamental properties of new semiconductor materials and to increase storage capacity, decrease power consumption, and vastly accelerate processing speed.The NSF award will support a PhD student and postdoctoral researcher, as well as an outreach program to inspire curiosity and engagement of K-12 and underrepresented students in materials for next-generation electronics. Specifically, Dr. Fullerton has developed an activity where students can watch the polymer electrolytes used in this study crystallize in real-time using an inexpensive camera attached to a smart phone or iPad. The CAREER award will allow Dr. Fullerton to provide this microscope to classrooms so that the teachers can continue exploring with their students. Tevis Jacobs, Assistant Professor of Mechanical Engineering and Materials Science ($500,000)Title:Understanding Nanoparticle Adhesion to Guide the Surface Engineering of Supporting Structures (#1844739) Summary: Although far thinner than a human hair, metal nanoparticles play an important role in advanced industries and technologies from electronics and pharmaceuticals to catalysts and sensors. Nanoparticles can be as small as ten atoms in diameter, and their small size makes them especially susceptible to coarsening with continued use, which reduces functionality and degrades performance. Dr. Jacobs will utilize electron microscopy to develop new methods to measure the attachment and stability of nanoparticles on surfaces under various conditions, allowing researchers to enhance both surfaces and nanoparticles in tandem to work more effectively together.Additionally, Dr. Jacobs and his lab group will engage with the University of Pittsburgh School of Education and a local elementary school to create and nationally disseminate surface engineering-focused curricular units for sixth- to eighth-grade students and professional development training modules for teachers. Carla Ng, Assistant Professor of Civil and Environmental Engineering ($500,000)Title:Harnessing biology to tackle fluorinated alkyl substances in the environment (#1845336) Summary: Per- and polyfluorinated alkyl substances (PFAS) are man-made chemicals that are useful in a variety of industries because of their durability, but do not naturally break down in the environment or human body. Because of their useful oil- and water-repellent properties, PFAS are used in many consumer products, industrial processes, and in firefighting foams, but unfortunately, their manufacturing and widespread use has contributed to the undesired release of these chemicals into the environment. With evidence showing that PFAS may have adverse effects on human health, Dr. Ng wants to further investigate the potential impacts of these chemicals and identify ways to remove them from the environment. She plans to elevate K-12 and undergraduate education through the use of collaborative model-building in a game-like environment. Dr. Ng in particular will utilize the agent-based modeling language NetLogo, a freely available and accessible model-building tool that can be equally powerful for cutting edge research or for students exploring new STEM concepts in science and engineering. Gelsy Torres-Oviedo, Assistant Professor of Bioengineering ($805,670)Title: Novel human-in-the loop approach to increase locomotor learning Summary: Many stroke survivors who suffer from impaired gait benefit from rehabilitation using robotics. Unfortunately, motor improvements following training are not maintained in the patient’s daily life. Dr. Torres-Oviedo hypothesizes that some of these individuals have difficulty perceiving their asymmetric movement, and she will use this project to characterize this deficit and indicate if split-belt walking - in which the legs move at different speeds - can correct it. Her lab will track how patients with brain lesions perceive asymmetries in their gait. They will then measure how their perception is adjusted once their movements are adapted in the split-belt environment. In the second part of this study, the lab will use these data and a unique method to manipulate how people perceive their movement and create the illusion of error-free performance during split-belt walking. The goal is for the changes in their movements to be sustained in the patient’s daily life. Dr. Torres-Oviedo will also use this project as a way to increase the participation of students from underrepresented minorities (URM) in science and engineering. She will recruit, mentor, and prepare URM students from K-12 and college to pursue advanced education, with the ultimate goal of broadening the professional opportunities for this population. ###

Expect more blackouts unless we invest in our energy grid

Electrical & Computer

Gregory F. Reed is a professor and director of the Energy GRID Institute at the University of Pittsburgh’s Swanson School of Engineering. This op-ed appeared in The Hill on Saturday, August 10, 2019. Even before summer’s hottest months, utility providers in California warned they might cut power on windy days to prevent wildfires caused by falling power lines. In Texas, utilities said they would urge consumers to conserve electricity to avoid the need for rolling blackouts when record heat leads to record electricity usage that can overwhelm the system. Despite having one of the most reliable electricity systems in the country, much of midtown Manhattan and parts of the Upper West Side were plunged into darkness last month, 42 years to the day of the New York City blackout of 1977. A contributing factor was that some of the electrical infrastructure of the Con Edison system in the city is old enough to have been involved in both outages. A week after the blackout, Con Ed had to cut power to more than 50,000 customers in Brooklyn and other boroughs to prevent a larger outage. Across the country, and especially in major metropolitan areas, the power grid is in need of repairs, updates and, in many cases, redesign. As demand for electricity continues to increase, we cannot ignore the impact of our energy production on the environment and vice versa. These blackouts underscore a significant, persistent threat to our country’s electric power grid — and they won’t be the last. Nearly 600,000 miles of high-voltage transmission lines and approximately 15,000 interconnected substations serve the U.S.’s intricate power grid. Nearly 5.5 million miles of low-voltage distribution circuits and 60,000 stations serve large cities and remote rural areas. Much of the infrastructure and equipment is over 40 years old (in some cases, 80 years), built during times of prosperity after both world wars, with technology that would be recognizable to George Westinghouse and Nikola Tesla, the inventors of our current system, were they to visit a power station today. Those stations did not anticipate today’s power demands, nor were they designed to easily integrate sustainable power generation or two-way interactions between the grid and consumers. New resources such as solar, wind, wave and battery energy systems are based on power electronics and direct current (DC) technologies. But the grid was constructed using alternating current (AC) and moves electricity primarily in one direction from large-scale centralized resources to consumers. Today, many new resources are being located on the consumer, or distribution end of the system, presenting a challenging paradigm for our energy infrastructure and markets. Overhauling the power grid would be an enormous endeavor — a modern-day equivalent of building the 1940s highway system across the country — but it is necessary. We need a national power grid infrastructure that is reliable and sustainable, as well as resilient to the challenges of a changing climate. We need the power equivalent of our commitment to the Manhattan Project or NASA’s endeavor in the 1960s to put a man on the moon. And while space exploration is important to our future, the immediate need to secure and modernize our nation’s electrical infrastructure remains much more critical and necessary. Because we no longer are tethered to coal as the primary energy source, “microgrids” are one way that communities can provide independent energy from sustainable sources such as solar power and wind farms. Smaller grids can restore power more rapidly in the event of an outage and better meet the demands of a concentrated area. But even this isn’t enough to secure a sustainable, efficient and secure grid. A national high-voltage direct current (HVDC) system would create opportunities for technological leadership and economic growth for this country. It would maximize investments in large-scale energy developments in remote areas of the country, as well as offshore. The redesigned architecture would be designed with DC in mind, meaning consumers would see increased efficiency and lower operating costs. Though it would be no small investment, it’s one that the United States should prioritize. From construction to advanced research and development, from engineering to innovative technology, there would be blue-collar and white-collar employment opportunities that would benefit communities across the country — the 21st century equivalent of Roosevelt’s New Deal. July’s power outage in New York City was just a glimpse at what could happen if our overtaxed power grid were to fail on a larger scale: trains interrupted, buildings hot and quiet, and people left in the dark, some stranded on elevators. It is worth considering that nearly everything we do in modern society is dependent upon the reliable supply of electricity. Our nation’s power grid is at a critical crossroads.We need to seize this opportunity to protect our nation’s security and our way of life. ###

Bioengineering, Chemical & Petroleum, Civil & Environmental, Electrical & Computer, Industrial, MEMS

PITTSBURGH (July 9, 2019) ... A $10 million grant from the National Science Foundation (NSF) is funding a new supercomputer at the Pittsburgh Supercomputing Center (PSC), a joint research center of Carnegie Mellon University and the University of Pittsburgh. In partnership with Hewlett Packard Enterprise (HPE), PSC will deploy Bridges-2, a system designed to provide researchers in Pennsylvania and the nation with massive computational capacity and the flexibility to adapt to the rapidly evolving field of data- and computation-intensive research. Bridges-2 will be available at no cost for research and education, and at cost-recovery rates for other purposes. "Unlocking the power of data will accelerate discovery to advance science, improve our quality of life and enhance national competitiveness," said Nick Nystrom, PSC's chief scientist and principal investigator (PI) for Bridges-2. "We designed Bridges-2 to drive discoveries that will come from the rapid evolution of research, which increasingly needs new, scalable ways for combining large, complex data with high-performance simulation and modeling." Bridges-2 will accelerate discovery to benefit science, society, and the nation. Its unique architecture will catalyze breakthroughs in critically important areas such as understanding the brain, developing new materials for sustainable energy production and quantum computing, assembling genomes of crop species to improve agricultural efficiency, exploring the universe via multimessenger astrophysics and enabling technologies for smart cities. Building on PSC's experience with its very successful Bridges system, Bridges-2 will take the next step in pioneering converged, scalable high-performance computing (HPC), artificial intelligence (AI) and data. Designed to power and scale applications identified through close collaboration with the national research community, Bridges-2 will integrate cutting-edge processors, accelerators, large memory, an all-flash storage array and exceptional data-handling capabilities to let researchers meet challenges that otherwise would be out of reach. By enabling AI to be combined with simulation and modeling and through its focus on ease of use and researcher productivity, Bridges-2 will drive a new era of research breakthroughs. "Bridges-2 is a major leap forward for PSC in high-performance computing and data analytics infrastructure and research," said Alan D. George, Interim Director of PSC. "PSC is unique in combining the strengths of two world-class universities (CMU and Pitt) and a world-class medical center (UPMC). Bridges-2 will amplify these strengths to fuel many new discoveries." "Enabling the execution of science, engineering and non-traditional workflows at scale while leveraging and further developing artificial intelligence is vital to keeping the United States at the forefront of scientific discovery now and into the future," said Paola Buitrago, Director of Artificial Intelligence & Big Data at PSC and co-PI of Bridges. "The Bridges-2 system is the way to realize this and more. I look forward to all the knowledge, discoveries and progress this new system will produce." Bridges-2's community data collections and user-friendly interfaces are designed to democratize participation in science and engineering and foster collaboration and convergence research. The Bridges-2 project includes bringing the benefits of scalable data analytics and AI to industry, developing STEM talent to strengthen the nation's workforce and broadening collaborations to accelerate discovery. The NSF is funding Bridges-2 as part of a series of awards for Advanced Computing Systems & Services. "The capabilities and services these awards will provide will enable the research community to explore new computing models and paradigms," said Manish Parashar, Office Director for the Office of Advanced Cyberinfrastructure at NSF. "These awards complement NSF's long-standing investment in advanced computational infrastructure, providing much-needed support for the full range of innovative computational- and data-intensive research being conducted across all of science and engineering." Bridges-2 will be deployed in the summer of 2020. ###

NSF Awards $500,000 to Pitt Researchers to Create Neuromorphic Vision System Mimicking Human Sight

Bioengineering, Electrical & Computer

PITTSBURGH (June 19, 2019) —  Self-driving cars rely on their ability to accurately “see” the road ahead and make adjustments based on what they see. They need to, for instance, react to a pedestrian who steps out from between parked cars, or know to not turn down a road that is unexpectedly closed for construction. As such technology becomes more ubiquitous, there’s a growing need for a better, more efficient way for machines to process visual information. New research from the University of Pittsburgh will develop a neuromorphic vision system that takes a new approach to capturing visual information that is based on the human brain, benefitting everything from self-driving vehicles to neural prosthetics. Ryad Benosman, PhD, professor of ophthalmology at the University of Pittsburgh School of Medicine who holds appointments in electrical engineering and bioengineering, and Feng Xiong, PhD, assistant professor of electrical and computer engineering at the Swanson School of Engineering, received $500,000 from the National Science Foundation (NSF) to conduct this research. Conventional image sensors record information frame-by-frame, which stores a great deal of redundant data along with that which is useful. This excess data storage occurs because most pixels do not change from frame to frame, like stationary buildings in the background. Inspired by the human brain, the team will develop a neuromorphic vision system driven by the timings of changes in the dynamics of the input signal, instead of the conventional image-based system. “With existing neuromorphic camera systems, the communication between the camera and the computing system is limited by how much data it is trying to push through, which negates the benefits of the large bandwidth and low power consumption that this camera provides,” says Dr. Xiong. “We will use a spiking neural network with realistic dynamic synapses that will enhance computational abilities, develop brain-inspired machine learning to understand the input, and connect it to a neuromorphic event-based silicon retina for real-time operating vision.” This system will work more efficiently than existing technology, with orders of magnitude better energy efficiency and bandwidth. “We believe this work will lead to transformative advances in bio-inspired neuromorphic processing architectures, sensing, with major applications in self-driving vehicles, neural prosthetics, robotics and general artificial intelligence,” says Dr. Benosman. The grant will begin July 1, 2019, and is expected to last until June 30, 2022. ### About the Swanson School of EngineeringThe University of Pittsburgh’s Swanson School of Engineering is one of the oldest engineering programs in the U.S. and is consistently ranked among the top 25 public engineering programs by U.S. News & World Report.

Engineering Synergy

Electrical & Computer

PITTSBURGH (June 18, 2019) … Following almost two years of intense investigation, research, and feedback, the University of Pittsburgh’s Swanson School of Engineering is poised to begin a new chapter in the 126-year history of one of its departments. The Department of Electrical and Computer Engineering (ECE) received approval to adopt new curricula for its two undergraduate programs (electrical engineering, computer engineering) to provide greater synergy between the two fields, create more opportunities for hands-on learning, and address the needs of employers who demand that graduates have a greater breadth and depth of knowledge. The two new curricula will begin in fall 2019 for rising sophomores in these two majors and were greatly influenced by input from faculty, alumni, industry, and students. Alan George, department chair and the R&H Mickle Endowed Chair and Professor of Electrical and Computer Engineering, explained that the time was perfect to modernize and seamlessly integrate the two programs and encourage greater flexibility in learning. “The genesis of Pitt’s ECE program is one for the history books. The electrical engineering (EE) curriculum was born in 1893 from the minds of George Westinghouse and Reginald Fessenden, two of the leading engineering pioneers of the late 19th century, while creation of the computer engineering (CoE) program in 1996 was a response to the incredible growth of the industry,” Dr. George explained. “And yet, for several decades there was a disconnect between what would become two very integral fields. This split was a missed opportunity for strength from synergy, especially today when both electricity and computers are ubiquitous to everyday human life.” The beginning of the curricula redesign began shortly after Dr. George’s appointment as department chair in 2017, when there was already a growing desire by faculty and students to improve the two programs, especially in response to industry trends and new guidelines released by IEEE and ACM (the two leading professional societies in ECE). The effort then escalated in 2018 with major contributions from many ECE faculty members, and with the appointment of two new undergraduate program directors in ECE: Assistant Professor Samuel Dickerson, who would serve as the director for computer engineering; and Assistant Professor Robert Kerestes, who was appointed as director for electrical engineering. Dickerson and Kerestes are both triple alumni (B.S., M.S., PhD) of Pitt in their respective disciplines.  “We could not be more fortunate than to have Sam and Bob as outstanding young faculty and alumni, with a passion for Pitt and commitment to leading programs and teaching classes for the next generation of engineers that are even better than they had as students.” Four Strategic Curricular Changes According to Dickerson and Kerestes, the changes in each program follow four strategies: Following the students’ foundational first-year experience, the sophomore year for both majors features four, two-course sequences in analog hardware, digital hardware, software design, and applied math, with a strong balance of classroom and lab studies. A modernized suite of required courses is featured in the junior year, including six core courses and one advanced math course unique to each discipline, plus a new course on Junior Design Fundamentals for both majors. Senior year includes four discipline-specific electives, three technical electives, and one general elective, providing greater depth and the ability for students to develop specialties and explore other fields. Lastly, design concepts, skills, and experiences are greatly expanded throughout the two programs, both explicitly (new junior and upgraded senior design courses) and implicitly (design-oriented lab experiments in many new and upgraded courses). “One of the complaints we heard from recent graduates – and which we both experienced as students – is that we don’t let them have “fun” until senior year,” Dickerson said. “Like any engineering discipline, electrical and computer engineers are very hands-on people, and so it’s critical for students to engage in those activities earlier than senior year, as well as understand the integration of design with theory.” “The input of our visiting committee, alumni and industry was critical in helping us focus on integrating the electrical and computer engineering skills that decades ago were independent, but today are complementary and intertwined,” Kerestes added. “I also think that by leveraging the strengths of our department – for example, from power engineering and systems in EE to embedded computer systems and applications in CoE – we can integrate those in the junior year and better prep our students for employment in co-op or industry, or help them better decide whether they want to continue to graduate school.” Both Dickerson and Kerestes acknowledge the level of difficulty increases with the new curricula, but the changes will enable the students to do much more as electrical and computer engineers. And Department Chair George agreed that such challenges are necessary to better prepare students for an increasingly competitive global environment. “I think that, after our students graduate, each will find that the new curriculum has benefited them by making them more adaptable, nimble, and impactful engineers,” George said. “Just as Westinghouse, Fessenden, and the first computer engineers could only have theorized how our disciplines would evolve over the century, we need to prepare our students to adapt to the next technological breakthroughs that we haven’t yet imagined. It’s an exciting time for the ECE Department, and I’m looking forward to the response and success of our undergraduates.” ###

Pitt Team Makes Finals in Cornell Cup

Electrical & Computer

PITTSBURGH (June 11, 2019) —  A team of students from the University of Pittsburgh’s Swanson School of Engineering competed as finalists in this year’s Cornell Cup – Arm Enabled with their project, V2 Communications, an inter-vehicle communication network. The Cornell Cup – Arm Enabled is a design competition that invites engineering students to submit an invention or project featuring embedded technology. It offers finalists funding, access to expert reviews, and the opportunity to present their project at a two-day expo at the NASA Kennedy Space Center. The team competed against 11 other finalist teams from Worcester Polytechnic Institute, University of California - Irvine, Purdue University, Boston University, University of Pennsylvania, Virginia Tech, and Drexel University from May 3-4. The goal of V2 Communications is to develop an inter-vehicle communication network so that any cars with a Controller Area Network (CAN) bus system can share real-time driving data such as speed, acceleration, and engine status with other cars within 100 meters—information that may lead to fewer accidents and greater traffic throughput capacity on the road. The system includes security measures, ensuring it is resistant to packet injection and spoofing attacks. The team consisted of Haihui Zhu, rising junior in electrical and computer engineering, and Zachary M. Mattis, who graduated this semester with a bachelor degree in computer engineering. The pair were interested in the concept of cars “talking” to one another on the road and decided to pursue the project last fall. Sami Mian, doctoral candidate, and Sam Dickerson, PhD, assistant professor and director of the Undergraduate Computer Engineering program, served as advisors for the team. Now, the team will spend time researching the market and determining what’s next for V2 Communications. “There are some technology companies already working on vehicle-to-vehicle communications. For example, Peloton Technology focuses on automated delivery and provides truck platooning,” Zhu explains. “One of the next steps is to do research on these companies and understand the market need. We also plan to improve our V2 solution with mmWave sensors and 5G beamforming.” “This was a great opportunity for our students to think critically and apply the things they’ve learned in the classroom,” says Dr. Dickerson. “We’re proud of them for representing us well at the finals and look forward to seeing what the future has in store for V2 Communications.”

How Kevin Glunt Went From Struggling Student to Sending an A.I. Computer to the ISS

Electrical & Computer, MEMS, Student Profiles

Around a decade ago, Kevin Glunt was more interested in drawing cars than paying attention in class, with his parents threatening that he would repeat a grade of school if he didn’t stop. Now aged 24, he’s in awe as SpaceX has launched his team’s creation into orbit: A radiation-tolerant supercomputer that will be used in experiments on sensing, image processing, and machine learning, aboard the International Space Station. “All of our names are on the board, like etched on it,” Glunt told Inverse this week, prior to the launch. “It’s like, your name will be in space. And it’s really, really weird to think about that.” It’s not just a name in space: the computer, made by Glunt and his fellow researchers and students from the University of Pittsburgh, could pave the way for a faster future in space. More powerful systems at lower cost, and with more efficient power usage, represent another step toward more reliable research in orbit. Read the full story at inverse.com.

Pitt Electrical and Computer Engineering Professor Sam Dickerson Wins 2019 Board of Visitors Award

Electrical & Computer

PITTSBURGH (May 3, 2019) — Recognizing his role in developing undergraduate programs, innovative teaching and leadership in his field, Sam Dickerson, PhD, assistant professor of electrical and computer engineering, has won the 2019 Board of Visitors Award. “Dr. Dickerson is the epitome of a faculty member devoted to diversity for the benefits of all students, staff, and faculty, demonstrating leadership in student recruitment, student retention, community engagement, and student mentoring,” says Roberta A. Luxbacher, chair of the Board of Visitors.  “He has had a tremendous impact on the mission of the department and the school. The Board of Visitors is proud of accomplishments such as his, which are extremely important if the School is to continue to be recognized as a national force in engineering education and research." Dr. Dickerson serves as director of the undergraduate Computer Engineering program in addition to his teaching. He joined the Swanson School as assistant professor in 2015 after completing his PhD, MS and BS degrees in electrical and computer engineering (ECE) at Pitt. Examples of Dr. Dickerson’s dedication to the success of all students are abundant in the department. Dr. Dickerson pushed for examination space in ECE for students with disabilities and special needs and is the faculty founder of “Chat and Chew,” a diversity program in ECE meant to engage and support URM students. He also served as faculty lead in funding female ECE students to attend the annual Grace Hopper Conference; led an NSF project to create and study new teaching methods for broad demographic groups; and led the Hands-on-Science activity for Swanson’s Investing NOW Pre-College Program. Dr. Dickerson also advises the nearly 300 undergraduate students in Computer Engineering, one of the School’s largest programs. In addition to his leadership and mentoring roles, Dr. Dickerson is nationally recognized as an innovative and passionate educator. He has received NSF funding to implement new techniques in teaching electronics and has modernized the Senior Design Project course in a way that challenges students and pushes them out of their comfort zones. Dr. Dickerson received the School’s Outstanding Educator Award this year in recognition of this work. “Dr. Dickerson is consistently ranked by students as one of the best teachers in the School, and his commitment to the teaching profession is a model for every faculty member demonstrating great passion and commitment to teaching,” says Alan George, PhD, chair of the Electrical and Computer Engineering department.  “When he was asked to assume the leadership role as director of our undergraduate program in computer engineering in 2017, his response was amazing and refreshing, replying that he would be happy to serve in this role but regretful that it would mean a reduction by one in his teaching load each year.” The Board of Visitors Award includes a $5,000 grant to support the recipient’s scholarly activities. It was presented at the Board of Visitors Dinner on May 2, 2019.

New Pitt Supercomputer to Launch Into Space

Electrical & Computer, MEMS, Student Profiles

This story originally appeared in Pittwire. Reposted with permission. Additional coverage at Inside HPC. A novel supercomputer developed by a University of Pittsburgh team is set to journey to the International Space Station on May 1, continuing a NASA partnership meant to improve Earth and space science. (Editor’s note: The successful launch later occurred on May 4.) It will be “one of the most powerful space-qualified computers ever made and flown,” said Alan George, department chair of the Swanson School of Engineering’s Department of Electrical and Computer Engineering, who led Pitt researchers and graduate students on the project. On the space station, the supercomputer will serve as a research “sandbox” for space-based experiments on computing, sensing, image processing and machine learning. Researchers said the main objective of these experiments is progression toward autonomous spacecraft, like a more advanced version of the self-driving cars seen in Pittsburgh. This radiation-tolerant computer cluster, called the Spacecraft Supercomputing for Image and Video Processing (SSIVP) system, is part of the U.S. Department of Defense Space Test Program-Houston 6 mission (STP-H6), developed at the National Science Foundation Center for Space, High-performance, and Resilient Computing (SHREC). The system “features an unprecedented combination of high performance, high reliability, low power and reconfigurability for computing in the harsh environment of space, going beyond the capabilities of previous space computers,” said George, who’s also founder and director of SHREC. The project carries over from time’s spent with the University of Florida prior to moving to Pitt in 2017, when a pair of space computers developed by Pitt students and faculty was sent aboard the space station. Last year, the new space supercomputer embarked on a 1,400-mile land-based journey for rigorous testing, from NASA Goddard Space Flight Center in Greenbelt, Maryland, to the NASA Johnson Space Flight Center in Houston to the NASA Langley Research Center in Hampton, Virginia. Its final, much shorter and more meaningful trip will see it travel 250 miles skyward from NASA Kennedy Space Center in Cape Canaveral, Florida, to the space station with the SpaceX-17 mission on a Falcon 9 SpaceX rocket. Super powered Sebastian Sabogal and Evan Gretok, PhD students in electrical and computer engineering, pose by their workstation in SHREC (Center for Space, High-performance, and Resilient Computing), where they monitor their supercomputing cluster’s progress. They’ve worked on the cluster’s design, hardware configuration and image processing. (Aimee Obidzinski/University of Pittsburgh) The new space supercomputer is more than 2.5 times more powerful than its predecessor, which was launched to the space station with STP-H5 on SpaceX-10 in February 2017. It includes dual high-resolution cameras capable of snapping 5-megapixel images of Earth, for detailed aerial shots like the city of Pittsburgh, all in a system about the size of a breadbox. The H5 system will remain on the space station, working separately from the soon-to-be-launched H6 system on a dynamic set of space technology experiments until at least 2021. The H6 system is expected to be in service for three to four years after launch. The large amounts of data the new system captures will pose their own challenge. “There are limitations in communications between ground and spacecraft, so we’re trying to circumvent these limitations with high-performance onboard data processing to more quickly transfer data,” said Sebastian Sabogal, a third-year PhD student studying electrical and computer engineering. “We also want our systems to be highly responsive to processed sensor data to enable spacecraft autonomy, which would reduce the amount of human interaction needed to operate the spacecraft and interpret data.” “Everyone in the space community wants to build sensor systems that are more powerful and autonomous,” George said. “We must process the data where it’s gathered, which requires very powerful computers, but space is the most challenging place to build and deploy powerful computers.” Space, too, is a challenging place for computers to thrive due to high fluctuations in temperatures, strong vibrations during launch and higher levels of radiation — all of which can affect performance, said Sabogal. During its time in space, the supercomputer will gather and monitor data on weather patterns, deforestation, and the effects of natural disasters on Earth and the effects of space and radiation on electronic devices, among many applications in Earth and space science. A goldmine for students SHREC also is collaborating for the first time with the Swanson School of Engineering’s Department of Mechanical Engineering and Materials Science, with the latter designing, assembling and testing the system chassis to meet the structural requirements from NASA for the computing system. For students, these space missions are an opportunity to hone their engineering expertise and interact closely with experts at NASA and the U.S. Department of Defense. The Spacecraft Supercomputing for Image and Video Processing marks the first known instance of the “Pitt Script” in space. (Courtesy of Alan George) “When I initially came in, it was one of the big projects going on here,” said Evan Gretok, a second-year PhD student studying electrical and computer engineering. “I was asked if I was up for a challenge, and I was put on developing some of the flight software for some of the secondary objectives of the mission.” These secondary objectives include studies regarding flight services, hardware configuration and studies on image processing. Gretok also earned his master’s degree in the same field at Pitt this year, and he has been working with the NASA Marshall Space Flight Center in Huntsville, Alabama, to certify the supercomputer’s ground-station software for mission operations that will be controlled by Pitt researchers in the SHREC lab meets NASA standards. “It’s really humbling to be part of a team that has this kind of access to such innovative technology,” Gretok said. “The amount of opportunities that open up for Earth observation for data analytics and for these students to develop their own applications and algorithms is exciting to see.” Other leading researchers for the project include Matthew Barry, an assistant professor of mechanical engineering and materials science, who also works with the Center for Research Computing and was in charge of thermal modeling for the computer, and David Schmidt, an associate professor of mechanical engineering and materials science, whose team was in charge of the design and construction of the aluminum chassis to house the electronics, ensuring that it meets NASA specifications.

2019 Siemens Peter Hammond Scholarship Awarded to Ryan Brody

Electrical & Computer

PITTSBURGH (April 18, 2019) — Ryan Brody, a first-year MS student in electrical and computer engineering at the University of Pittsburgh Swanson School of Engineering, has been selected to receive this year’s Siemens Peter Hammond Scholarship for $10,000. The scholarship is named for Peter Hammond, inventor of the Perfect Harmony drive and long-time engineer at Siemens who is now retired. Hammond’s Perfect Harmony drive is a high-power machine that controls the speed of large motors; today, it is a key part of Siemens’ medium voltage variable frequency drive portfolio. The resulting energy savings on large pumps, fans, compressors, and other industrial equipment have had an enormous environmental impact, the carbon footprint equivalent of removing millions of cars from the road. The annual scholarship, which is in its third year, is open to any student in Electrical and Computer Engineering at the Swanson School. Students must complete an application, supplementing it with an essay, letters of recommendation, a resume and their transcript. “Peter Hammond represents the inventive thinking and hard work that is central to engineering,” says Brandon Grainger, PhD, associate director of the Electric Power Systems Laboratory and assistant professor of electrical and computer engineering at Swanson. “This scholarship selects students who are not only qualified academically but who also share those qualities that have made Peter a successful engineer.” The first Siemens Peter Hammond Scholarship recipient was Jacob Friedrich, MS EE, who is currently working at Aptiv on electric vehicles; the second was Thomas Cook, BS, who is currently pursuing his MS at Swanson and plans to go on for a PhD. Brody says he values learning and wants to use his experience to find solutions to interesting, practical problems and to mentor others. He plans to complete his master’s degree and pursue a PhD, studying power conversion in electric vehicles. “I hope my research will find a simple, energy efficient, low-cost, lightweight active battery cell balancing system for electric vehicles by integrating the cell balancing circuitry into the drive-train power electronics,” says Brody. “I’m grateful that this scholarship will help me achieve my goals of becoming a researcher, professor and entrepreneur.” The scholarship was presented April 10, 2019 and included a presentation by Jason Hoover, director of business development at Siemens Industry, called “Using Digitalization for Motors and Drives to Improve Productivity in Process Industries.” “We’re pleased to invest in our collective future through the Siemens Peter Hammond Scholarship,” says Hoover. “We know the recipients of this scholarship will go on to mold the future with the same passion and ingenuity that allowed Pete to imagine the Perfect Harmony and bring it to life.”

Electrical & Computer

PITTSBURGH (April 11, 2019) … This year’s Distinguished Alumni from the University of Pittsburgh Swanson School of Engineering have worked with lesson plans and strategic plans, cosmetics and the cosmos, brains and barrels and bridges. It’s a diverse group, but each honoree shares two things in common on their long lists of accomplishments: outstanding achievement in their fields, and of course, graduation from the University of Pittsburgh. This year’s recipient for the Department of Electrical and Computer Engineering is Robert Van Naarden, BSEE ’69, CEO of Delta Thermo Energy. The six individuals representing each of the Swanson School’s departments and one overall honoree representing the entire school gathered at the 55th annual Distinguished Alumni Banquet at the University of Pittsburgh’s Alumni Hall to accept their awards. James R. Martin, US Steel Dean of Engineering, led the banquet for the first time since starting his tenure at Pitt in the fall. “We like to ask our alumni what they remember most while at Pitt, and Robert said that his Pitt engineering education ‘prepared me for the real world not only for design engineering, which is how I started my engineering career, but even more importantly the discipline of critical thinking,’” says Dean Martin. “That education is apparent from the many things Robert has achieved—from the first minicomputer that he worked on in 1970 to the leadership in sustainable energy he provides today.” About Robert Van Naarden Robert Van Naarden began his technology career after earning Bachelor of Science degrees in Physics and Electrical Engineering (University of Pittsburgh) and Master of Science degrees in Computer Science and Electrical Engineering. While pursuing his PhD he was offered a position with Digital Equipment Corporation (DEC) to design defense critical systems computers. He was on the original design team of the PDP 11, which became the world’s most successful mini-computer. After migrating through various engineering and engineering management roles, he originated the idea to design and bring to market the world’s first microcomputer, the PDP 16, based partially on the successful PDP 11 design. He grew to be the youngest Profit and Loss Group Manager at DEC and managed its fastest growing business. While in Philadelphia, Mr. Van Naarden earned an Executive Master of Business Administration degree at the Wharton School of the University of Pennsylvania, sponsored by Digital. In 1979, he co-founded Convergent Technologies (CT). CT became the fastest growing company in the computer industry. He and his partner at Convergent started another company, Ardent Computer, which was focused on the single user supercomputer space. After four years, the company merged with its principal competitor, Stellar Computer, to form Stardent Computer. Two years later, at Rob’s direction, the company was sold by splitting it up into its four components/divisions. Mr. Van Naarden moved on to start and fix a variety of other companies: Supermac, Firepower, Netframe, AMT, Sensar and Authentidate, where he started the company as its founder and CEO. In 2004, Mr. Van Naarden became CEO of Empire Kosher Poultry, Inc, turning it into a profitable company within nine months after running at a loss for seven years. After four years, Mr. Van Naarden returned to his roots in technology and is currently the CEO of Delta Thermo Energy an alternative energy company which uses innovative technologies for converting waste materials to energy.

NSF Awards $500,000 to Pitt and CMU for Engineering Research on Thermoelectric Devices

Electrical & Computer

PITTSBURGH (April 8, 2019) — As much as half of all U.S. energy production each year is lost as waste heat, but new research led by the University of Pittsburgh Swanson School of Engineering, in collaboration with Carnegie Mellon University, seeks to make converting that heat back into usable electricity more efficient. Feng Xiong, PhD, assistant professor of electrical and computer engineering at the Swanson School, and Jonathan Malen, professor of mechanical engineering at CMU, received a $500,000 award from the National Science Foundation to develop a thermoelectric semiconductor using tungsten disulfide to convert waste heat into energy. Using a novel doping approach, they will enhance the tungsten disulfide’s electrical conductivity while lowering its thermal conductivity—it will be able to efficiently conduct electricity without conducting heat. Tungsten disulfide is thin and flexible, making it a promising new option with diverse potential uses. “Once we’ve developed an effective technique to improve thermoelectric efficiency, it will pave the way for the wide use of thermoelectric devices to scavenge heat from sources such as electronics and even the human body,” says Dr. Xiong. “A two-dimensional semiconductor like this would be useful for everything from high-performance 2D transistors to wearable electronics that harvest body heat for power.” The project length is three years, with a possible extension into a fourth. The award is split between Dr. Xiong’s lab ($270,000) and Dr. Malen’s lab ($230,000). The team will work closely with local communities to encourage students from all backgrounds to explore engineering careers and foster interest in nanotechnology. Outreach efforts will include lab demonstrations, summer internships and career workshops. “Climate change is a pressing concern in today’s world, and developing ways to use our resources more efficiently is critical,” says Dr. Xiong. “Converting waste heat into electricity could improve energy efficiency dramatically and sharply reduce greenhouse gas emissions. Through this project, we hope to encourage the next generation to explore even more innovative options for energy.”

Good Vibrations: Pitt Undergraduates Create a Device to Help Deaf Kids Experience Music Through Tactile and Visual Feedback

Bioengineering, Electrical & Computer, MEMS, Student Profiles

PITTSBURGH (April 4, 2019) … Through the Swanson School of Engineering’s The Art of Making class, an interdisciplinary group of eleven University of Pittsburgh undergraduate students connected with the Western Pennsylvania School for the Deaf (WPSD) and Attack Theatre to create a device that can help hearing-impaired children experience music and express themselves through dance. Attack Theatre holds a recurring dance workshop for three-to-six-year-olds at WPSD. The group previously tried using a Bluetooth speaker in a trash can to produce a vibratory effect that the children could touch and interact with, but this design was not kid-friendly and lacked mobility for lessons that necessitate free movement. The Pitt team saw an opportunity to take a fresh look at the problem and design a new system that addresses the needs of both the instructors and the children. However, with no hearing-impaired members, the undergraduates had to find a way to step into the shoes of their end users to better understand their needs. “This was a profoundly human-centered design problem with multiple stakeholders,” said Dr. Joseph Samosky, assistant professor of bioengineering and director of The Art of Making course. “A new technology, even if it works perfectly, is useless if it isn’t accepted by and accessible to the end user. This team of student innovators really understood and acted on that insight.” Issam Abushaban, a sophomore bioengineering and computer engineering student, said that the group learned more about their target audience from WPSD teachers. “We discovered that the rhythm of music and the visualization of colors can reflect a certain mood and affect the way that you feel,” he said. “That was something we really wanted to incorporate into our design.” To better understand the dance element of their task, the group participated in one of Attack Theatre’s workshops catered to deaf and hard-of-hearing children. “A lot of their dance moves were geared toward expressing an emotion, such as stomping to express anger or frustration or skipping to express joy,” said Farah Khan, a senior bioengineering student. “I think this demonstration gave us a different perspective and helped us view music in a new, productive way.” After completing their background research, the team decided to explore the use of both visual and tactile feedback for their design. They created several early prototypes, including a wrist strap with haptic motors and a disc “floor mat” with multi-hued illumination around the periphery. When the vibrating wrist strap was sampled by the children, the team learned the value of making early prototypes and getting feedback from their users to empirically test design concepts. “During our first round of testing, we wanted to pay attention to the reactions that the kids made, rather than focusing on the messages that the interpreter relayed,” said Abushaban. “Some of the kids seemed to be wary or afraid of the wrist strap so the lesson we learned from that meeting was that our product perhaps wasn’t kid-friendly. We then brainstormed new ideas of how to provide vibrational feedback in a more toy-like system.” The custom-designed plush toy houses sound transducers and a wireless communication system. The soft straps of the backpack/frontpack are adjustable, comfortable for the kids, and allow greater mobility for the dance workshop. Natalie Neal, a junior mechanical engineering and materials science student, was inspired to create patterns and hand sew a series of plush toy monkeys that incorporate a Bluetooth receiver, audio amplifier, vibrational transducers and battery power supply. This new iteration, dubbed Vibrance, can be worn either as a backpack or a “frontpack” - what the team calls “hug mode.” Additional testing and user feedback led to supplementing the tactile feedback with a projected visualizer that produces colorful circles based on the audio input. The Vibrance team presented their work at the Swanson School of Engineering’s fall 2018 Design Expo and swept the top three awards: first place in The Art of Making category, the People’s Choice Award, and the Best Overall Design. “Receiving those three awards really validated all of the hard work we did throughout the semester,” said Khan. The students’ innovative design has also received an enthusiastic response from kids, teachers, and parents. One parent of a child at WPSD wrote to the team, “I hope I’ll get the chance to see my son experience the vest vibration device. What an awesome idea!” Dr. Samosky was recently awarded a Provost’s Personalized Education Grant to support high-potential – and potentially high-impact – student design projects like Vibrance, enabling them to continue beyond the class in which they originate and be nurtured toward real-world impact. The Vibrance team will continue to develop and improve Vibrance under this new Classroom to Community initiative in Dr. Samosky’s lab. The goal is to create a device that meets the needs of both WPSD and Attack Theatre, but most importantly, the team wants to continue to positively affect the lives of the children using their device. As stated by Jocelyn Dunlap, a senior communication science student, “We are heading back to WPSD to continue building a project that claims a spot in all of our hearts.” ### This video of the Vibrance project, also created as part of the students’ coursework in The Art of Making, shows the system in action as it is used by instructors and kids at WPSD and with Attack Theatre. The Vibrance team includes, Issam Abushaban, a sophomore bioengineering and computer engineering student; Dani Broderick, a senior mechanical engineering student; Tom Driscoll, a junior computer engineering student; Jocelyn Dunlap, a senior communication science student; Austin Farwell, a junior mathematics student; Farah Khan, a senior bioengineering student; Stephanie Lachell, a senior mechanical engineering student; Evan Lawrence, a junior mechanical engineering student; Natalie Neal, a junior materials science and engineering student; Jesse Rosenfeld, a junior mechanical engineering student; and Caroline Westrick, a junior bioengineering student.

Swanson School of Engineering Names Sam Dickerson as 2019 Outstanding Educator

All SSoE News, Electrical & Computer

PITTSBURGH (March 22, 2019) — The University of Pittsburgh Swanson School of Engineering has presented Sam Dickerson, assistant professor of Electrical and Computer Engineering and director of the Computer Engineering undergraduate program, with this year’s Outstanding Educator Award. This competitive award recognizes his excellence in teaching and innovative work in developing and improving the department’s undergraduate program. The award includes a $2,000 grant to further enhance the recipient’s teaching. Dr. Dickerson joined the Swanson School as assistant professor in 2015 after completing his PhD, MS and BS degrees in electrical and computer engineering at Pitt. In addition to teaching, Dr. Dickerson plays an influential role in the development and improvement of the ECE and EE curriculums, with enthusiasm that does not go unrecognized by his peers. “Sam has modernized the way we teach our Senior Design Project course in a way that challenges the students and pushes them out of their comfort zones,” says Amro El-Jaroudi, associate professor of Electrical and Computer Engineering. “He has innovated in all aspects of the course: group formation, project selection, progress monitoring and project presentation. The impact of his hard work was immediately evident in the quality and depth of the designs and products created by the students.” Pushing students out of their comfort zone, while unreservedly providing the support they need, is a hallmark of Dr. Dickerson’s teaching style. “Dr. Dickerson is one of those professors who is so passionate about what he teaches that it makes students more excited to learn the material,” says Abigail Wezelis, a recent graduate who took several of Dr. Dickerson’s courses and served as a teaching assistant for his Advanced Digital Design course. “He strives to find real-world examples of the concepts that he teaches and is not afraid to teach relevant cross-disciplinary material in his classes.” “I’ve found that when students don’t see the big picture or understand how what they are learning fits in, then they quickly categorize it as being unimportant,” says Dr. Dickerson. “In order to combat this, through both lectures and laboratory exercises, I constantly give them examples where they can see how what they are learning is applied in industry.” Nominators noted that abundant examples of Dr. Dickerson’s method can be found throughout his courses. For example, in a recent course covering digital electronics, he showed students datasheet parameters, which serve as instruction manuals for electronic components, from real integrated circuit processes. According to Dickerson, these real-world examples showed students exactly why the material is relevant and how they, as future designers, will use what they are learning. In addition to teaching, Dr. Dickerson personally serves as an advisor and mentor to the over 300 students in the Computer Engineering undergraduate program. “When I asked him in 2017 to assume the leadership role as director of our undergraduate program in computer engineering, a major expansion to his faculty role, his response was amazing and refreshing, replying that he would be happy to serve in this role but regretful that it would mean a reduction by one in his teaching load each year,” says Alan George, professor and department chair of Electrical and Computer Engineering. “He truly loves working with and helping students; it is his calling and passion.” “The most important thing in teaching is to care about your students,” continues Dr. Dickerson. “This principle helps me overcome many of the flaws I have as an educator and drives me to work hard at improving my teaching abilities. I care deeply about student success and am willing to do whatever it takes to make sure that my students learn.”

Pitt researchers receive $550,000 NSF CAREER award to develop new brain-computer therapy method for people with autism

Bioengineering, Electrical & Computer

PITTSBURGH (March 21, 2019) … Autism was first described by U.S. researchers more than 70 years ago, and today the Centers for Disease Control and Prevention (CDC) estimates that 1 in 59 children are identified with autism spectrum disorder (ASD), affecting more than 3.5 million Americans. Although clinical techniques are used to help patients with ASD respond to stress and other factors, none are known to couple with technology that could monitor brain response in real time and provide the patient with feedback. However, thanks to a $550,000 award from the National Science Foundation, engineers at the University of Pittsburgh and clinicians at the UPMC Western Psychiatric Hospital, a new intervention using electroencephalography (EEG)-guided, non-invasive brain-computer interface (BCI) technology could complement clinical treatments and improve emotion regulation in people with ASD. The multidisciplinary team includes Murat Akcakaya, PhD, assistant professor of electrical and computer engineering at Pitt’s Swanson School of Engineering, and Carla A. Mazefsky, PhD, associate professor of psychiatry and psychology in Pitt’s Department of Psychiatry. The proposal is funded through an NSF CAREER award, which supports early-career faculty who have the potential to serve as academic role models in research and education and to lead advances in the mission of their department or organization.“People on the autism spectrum today have access to effective clinical strategies or technologies, but none are coupled effectively to provide real-time feedback in real-life activities. This limits reinforcement techniques that the patient can utilize on his or her own, without the need for a clinical appointment,” Dr. Akcakaya explained. “However, by utilizing EEG to couple clinical techniques with BCI technologies, we can develop a closed-loop system that will help patients better learn how to recognize emotional triggers and respond with appropriate techniques generalizing the effects of clinical treatment strategies to real-life activities.” Akcakaya and Mazefsky will develop social interaction scenarios in virtual environments while recording EEG responses simultaneously in order to detect patterns that represent changes in distress levels. The virtual scenario will then present audio or visual cues to help remind them how to handle stress. The project will also develop new machine learning algorithms and neuroscience methods to identify EEG features associated with emotion regulation to classify between distress and non-distress conditions, and to distinguish among different distress levels.The two will also investigate the promise of these EEG and virtual reality approaches within the context of Mazefsky’s randomized controlled clinical trial funded by the US Department of Defense. The clinical trial is testing the efficacy of an intervention Mazefsky and colleagues developed, called the Emotion Awareness and Skills Enhancement (EASE) program, in 12- to 21-year-old verbal youth with ASD. “EASE emphasizes awareness of one’s own emotional responses as a foundational skill that promotes the ability to manage intense negative emotions, which is taught through mindful awareness,” Mazefsky explained. “By coupling the clinical strategies we teach in EASE with technological interventions, we believe we can enhance patients’ ability to distinguish different distress levels and therefore potentially reap even greater (and more generalized) benefit.”The CAREER award will also enable Akcakaya to develop courses related to the research and outreach activities to promote STEM and ASD research to K-12 populations and the broader public. Outreach will focus especially on individuals with ASD, their families, and caretakers.  “Early diagnosis and intervention can help patients with ASD and their families improve quality of life, and so providing clinicians with a new tool that both enhances and reinforces what patients learn is critical to closing the loop between triggers and responses,” Akcakaya said. “Additionally machine learning based on biological responses could also be integrated in to the existing technologically driven intervention techniques targeting patients across the autism spectrum.  Eventually, the technology could be incorporated in an accessory like a smart watch or glasses, enhancing patient privacy and building confidence.” ###

Lights, Camera, Action: Pitt iGEM team captures silver medal for their “Molecular Movie Camera”

Bioengineering, Electrical & Computer, Student Profiles

PITTSBURGH (January 29, 2019) … The ability to measure and record molecular signals in a cell can help researchers better understand its behavior, but current systems are limited and provide only a “snapshot” of the environment rather than a more informative timeline of cellular events. In an effort to give researchers a complete understanding of event order, a team of University of Pittsburgh undergraduate students prototyped a frame-by-frame “video” recording device using bacteria. The group created this project for the 2018 International Genetically Engineered Machine (iGEM) competition, an annual synthetic biology research competition in which over 300 teams from around the world design and carry out projects to solve an open research or societal problem. The Pitt undergraduate group received a silver medal for their device titled “CUTSCENE.” The iGEM team included two Swanson School of Engineering students: Evan Becker, a junior electrical engineering student, and Vivian Hu, a junior bioengineering student. Other team members included Matthew Greenwald, a senior microbiology student; Tucker Pavelek, a junior molecular biology and physics student; Libby Pinto, a sophomore microbiology and political science student; and Zemeng Wei, a senior chemistry student. CUTSCENE aims to show a “video” of cellular activity by recording events in the cell using modified CRISPR/Cas9 technology. Hu said, “By knowing what time molecular events are happening inside of a cell, we are able to better understand a cell's history and how it responds to external stimuli.” Their system improved upon older methods that could only record the levels of stimuli at a single point in time. They used a movie analogy to illustrate their objective. “Try guessing the plot of a movie by looking at the poster; you can get an idea of what is going on, but to really understand the story, you need to watch the film,” said Becker. “Unless researchers are taking many snapshots of the cellular activity over time, the image doesn’t give any sense of causality. You can see that the molecule is there, but you don't know where it has been or where it is going.” For their project, the iGEM team used modified CRISPR/Cas9 technology called a base editor. The CRISPR/Cas9 system contains two key components: a guideRNA (gRNA) that matches a specific sequence of DNA and a Cas9 protein that makes a cut at the specific sequence, ultimately leading to the insertion or deletion of base pairs - the building blocks of DNA. In addition to these components, a CRISPR/Cas9 base editor contains an enzyme called cytidine deaminase that is able to make a known single nucleotide mutation at a desired location of DNA. “We achieved a method of true chronological event recording by introducing recording plasmids with repeating units of DNA and multiple gRNA to direct our base editor construct,” said Hu. “This technique will provide an understanding of the order in which molecules and proteins appear in systems.” “A recording plasmid can be thought of as a roll of unexposed film, with each frame being an identical sequence of DNA,” explained Wei. “A single-guideRNA (sgRNA) directs the CRISPR/Cas9 base editor to move along the recording plasmid, making mutations at a timed rate and constantly shifting which frame is in front of our base editor. Activated by the presence of a stimulus, another sgRNA can mark the current frame.” The iGEM team’s approach to this technology will allow them to figure out which molecules are abundant at specific times and perhaps reveal hidden, causal relationships. The information gathered from the device has many potential applications and may allow researchers to develop medicines and therapies based on the timing of the cellular malfunction. “The team did a tremendous amount of lab work over the summer, implementing the cellular event recording methodology,” said Alex Deiters, a professor of chemistry at Pitt who helped advise the iGEM team. “Most importantly, the students developed this clever idea on their own by first identifying a current technology gap and then applying modern gene editing machinery to it. The silver medal is well-deserved!” In addition to Dr. Deiters, the 2018 Pitt iGEM team was advised by Dr. Jason Lohmueller, American Cancer Society Postdoctoral Fellow in the Department of Immunology; Dr. Natasa Miskov-Zivanov, Assistant Professor of Electrical and Computer Engineering, Bioengineering, and Computational and Systems Biology; Dr. Sanjeev Shroff, Distinguished Professor and Gerald E. McGinnis Chair of Bioengineering; and Dr. Cheryl Telmer, a Research Biologist at Carnegie Mellon University. Funding for the 2018 Pitt iGEM effort was provided by the University of Pittsburgh (Office of the Senior Vice Chancellor for Research, Honors College, Kenneth P. Dietrich School of Arts and Sciences, Department of Biological Sciences, Department of Chemistry, Swanson School of Engineering, Department of Bioengineering, and Department of Electrical & Computer Engineering), New England Biolabs (NEB), and Integrated DNA Technologies (IDT). ###
