Xu Xu is an associate professor whose research mainly focuses on human motion data analysis and theoretical human biomechanical modeling with an emphasis on safety promotion. Xu’s research has been supported by the National Science Foundation (Cyberlearning, NRI, IUSE), the National Institute of Occupational Safety and Health and NC State’s Research and Innovation Seed Funding. He has co-authored more than 80 journal articles and conference proceedings on the aforementioned research topics and received the C. A. Anderson Outstanding Faculty Award and Goodnight Early Career Innovator Award.

Xu teaches undergraduate and graduate courses related to human factors and ergonomics, including ISE352 (Fundamentals of Human-Machine Systems Design), ISE 541 (Occupational Safety Engineering), ISE 544 (Occupational Biomechanics) and ISE 794 (Advanced Biomechanical Modeling).

Prior to joining the NC State faculty, Xu started his career as a postdoctoral research fellow in the School of Public Health at Harvard University. From there he became a research scientist at the Liberty Mutual Research Institute for Safety where he received a best-paper and outstanding scientific contribution awards multiple times.
