Yanfei Gao

Professor

Biography

Prof. Gao graduated with the highest honor from Tsinghua University (Beijing) in 1999 with a BS in Engineering Mechanics and a Dual BS in Computer Science. He then obtained his MA and PhD degrees in the Department of Mechanical and Aerospace Engineering, Princeton University (New Jersey) in 2001 and 2003, respectively. From 3/2003-7/2005, Dr. Gao worked as a post-doctoral research associate in the solid mechanics group at Brown University (Rhode Island). Since joining UT/ORNL in 8/2005, Dr. Gao has built up his research group on theoretical and computational studies of small scale mechanical behavior, failure of advanced structural materials, thin film heterostructures, and contact and friction. He was also a Joint Faculty member with Oak Ridge National Laboratory in 2005-2018. By 8/2020, Prof. Gao has authored or co-authored about 150 journal papers (including 19 in Acta Materialia and 14 in Journal of the Mechanics and Physics of Solids) and has made over 70 invited presentations at national/international conferences and academic institutions (including 2 invited talks at Gordon Research Conferences).
