overview

I am a Research Assistant Professor in the Department of Bioengineering. I am a bioengineer with research expertise in the field of gait biomechanics and fall prevention. I have over ten years of research experience with a focus on slips and falls. My previous experience as the Laboratory Manager and Research Coordinator at the University of Pittsburgh Human Movement and Balance Laboratory has helped to establish my vast array of technical knowledge while refining my biomechanical research skill set. I am available to provide advice and expertise on conducting biomechanics experiments and analyzing data. Additionally, I can provide laboratory space and equipment necessary to collect experimental aims, this includes motion capture, forceplatforms, EMG, accelerometers, harness system, anthropometers, balance measurement, strength testing, pertubation systems and custom equipment. My research interests include gait biomechanics, injury prevention in healthy and clinical young/elderly adult populations, footwear, ergonomics, fatigue, and prosthetics.
