Yuanli Bai is currently an associate professor at the UCF Department of Mechanical and Aerospace Engineering. He obtained his Ph.D. in mechanical engineering from the Massachusetts Institute of Technology in 2008. He obtained his bachelor's and master's degrees from the Department of Automotive Engineering from Tsinghua University in 2000 and 2003, respectively. While at MIT, he worked under the supervision of Professor Tomasz Wierzbicki, the director of the impact and crashworthiness lab. Prior to joining UCF in 2011, he was a mechanical engineer at the General Electric Global Research Center in Niskayuna, New York.

Bai’s current research is focused on plasticity, fracture and fatigue testing, analysis and simulation for various engineering materials, including lightweight metals, metallic matrix nano-composites, polymer matrix composites and soft tissue materials. He operates the Lab of Solid and Structure Mechanics under the MAE department. Bai has published numerous papers in the field's most highly rated journals and conference proceedings.
