Dr. Xiaohan (Jum) Zhang (xzhang11@stanford.edu)

I am currently a Postdoc researcher in Stanford University, working with Professor Wei Cai on modeling dislocation nucleations and dynamics in semiconductor, funded by Samsung Semiconductor Inc.

From 2011 to 2015, I was a PhD student in Material Mechanics and Computing group. My advisor is Professor Amit Acharya on field dislocation mechanics which is a modern plasticity PDE theory developed from Kroner, Mura, etc. I have also worked closely with Professor Noel Walkington and Professor Jacobo Bielak.

In 2014, I worked as an intern reseacher in material science department of Oak Ridge National Lab where I have worked closely with Professor Robert Dodds and Dr. Sham Sam on modeling creeping of metals in nuclear plants.

From 2007 to 2010, I am a master student in Hydraulic Department of Tsinghua University. My advisor is Professor Qiang Yang. We use in-house nonlinear finite element code TFINE to give stability analysis of huge hydraulic projects.
