My research focuses on the advancement of scientific knowledge and the development of innovative sensing and data analytics to tackle built environment issues, specifically to address the resilience, sustainability and safety issues of civil structural systems. The overall aim of this integrated interdisciplinary paradigm is to develop intelligent infrastructure systems and buildings, enhance the resilience and sustainability of our living communities, and make our built environment safer under “normal” operating conditions, intermediate stress conditions, and natural, manmade and technological hazard events. My research interests include the following interconnected thrusts:

  • Structural Informatics and Intelligent Structures
  • Machine Learning and Big Data Analytics
  • Data-driven Assessment of Structural Reliability and Resilience
  • Earthquake Engineering and Structural Dynamics
  • Ambient Seismic Interferometry for Temporal Structural Monitoring
  • Computational Inverse Problems and Uncertainty Quantification
  • Computational Mechanics: eXtended Finite Element Methods (XFEM) 
  • Forbes 30 Under 30 in Science, Forbes Magazine, 2018 Citation: Hao Sun’s research uses analtyics and machine learning combined with internet-of-things enabled sensors to track of the health of buildings, and detect reparable damage before there’s a bigger catastrophe. His team has built a prototype system, allowing them to observe ambient vibrations affecting the building and modeling its structural health.
