Prof. Wei Cai at the Mechanical Engineering Department of Stanford University is seeking a postdoctoral researcher to lead a project on the modeling of grain structure evolution in the surface layer under friction. The major task of this project is the development of a phase field model for grain/sub-grain structure evolution under friction. It is likely that molecular dynamics and dislocation dynamics simulations would be required as well to obtain a good physical understanding of the process. The postdoctoral researcher is also expected to collaborate with external experimentalists working on this project. A suitable candidate should have strong background on computational materials science, solid mechanics, and parallel programming. Prior experience with phase field method, dislocation dynamics and/or molecular dynamics simulations is highly desirable. To apply, please email Prof. Wei Cai <caiwei [at] stanford.edu> a CV and provide 2-3 names as references.
