Dr. Yanfei Gao
Assistant Professor
Ph.D., Princeton University: Nanoscale Domain Stabilities on Solid Surfaces and Guided Self-Assembly
Brief Bio
Dr. Gao earned his bachelor’s degree with the highest honor in the Department of Engineering Mechanics, Tsinghua University, Beijing, China in 1999, and his M.A. and Ph.D. degrees in the Department of Mechanical and Aerospace Engineering, Princeton University, New Jersey, in 2001 and 2003, respectively. Advised by Prof. Zhigang Suo, Dr. Gao’s thesis work identifies and simulates mechanisms of mechanically and/or electrically induced compositional self-assembly at nanoscale, and also investigates how to manipulate the self-organized patterns by symmetry breaking, strain engineering, and guided self-assembly. From March 2003 to July 2005, Dr. Gao worked as a post-doctoral research associate, with Prof. Allan F. Bower and Prof. Kyung-Suk Kim, in the Division of Engineering, Brown University. Supported by the General Motors/Brown Collaborative Research Lab on Computational Materials Research, his work includes multiscale modeling and experiments on surface plasticity and adhesion, microstructural evolution, and structural integrity. Since August 2005, Dr. Gao is a tenure-track Assistant Professor in Materials Science and Engineering, University of Tennessee, and also holds a joint faculty position at the Computational Materials Science Group, Oak Ridge National Laboratory. His current research interests focus on mechanics modeling of microstructural evolution, crystal plasticity at small length scales, constitutive behavior of amorphous alloys, etc., most of which are motivated from his colleagues’ experiments at UT and ORNL. Dr. Gao has authored or co-authored 20 technical papers, and has been actively involved in participating and organizing professional conferences.
