Professional Experiences

8/1/2005~present, Assistant Professor of Materials Science and Engineering, University of Tennessee at Knoxville; joint faculty in the Computational Materials Science group, Oak Ridge National Laboratory.

3/2003~7/2005, Research associate at Brown University (with A.F. Bower and K.-S. Kim)

As a member in the General Motors/Brown Collaborative Research Lab (CRL) on Computational Materials Research, conducting researches on

§         Multiscale modeling and experiments on surface plasticity and adhesion. A particular emphasis is placed on dislocation plasticity of indentation of stepped surface.

§         Simulation of microstructural evolution with cohesive zone, crystal plasticity, grain boundary motion, grain boundary diffusion etc.

§         Adhesive, viscoelastic indentation.

§         Mechanisms of tribolayer formation of Si-Al composite under repeated sliding.

9/1999~2/2003, Ph.D thesis: Nanoscale domain stabilities on solid surfaces and guided self-assembly, (with Z. Suo at Princeton University)

My thesis work identifies and simulates mechanisms of mechanically and/or electrically induced compositional self-assembly at nanoscale. Pattern formation and evolution are studied in a non-equilibrium thermodynamic framework and a phase-field model for computer simulation. We also investigate how to manipulate the self-organized patterns by symmetry breaking, strain engineering, and guided self-assembly.
