Research Activities and Interests One of my major research interests is in studying the emergent properties of interacting systems, both in and far away from equilibrium. In this regard, I have been working on the critical behaviors of disordered (Griffiths) ferromagnets near the Griffiths-ferromagnetic transition. I have also been working on non-equilibrium dynamics in material microstructures. I have been applying the phase field crystal (pfc) model to various multi-scale problems in pure material and binary alloys; these include grain coarsening, diffusion on atomic scales, solidification, defect (dislocation and domain wall) dynamics, elasticity and plasticity, as well as the Portevin-Le Chatelier (PLC) effect. My other focus is to study how pattern evolves. My work is mainly on the geophysical pattern formation in carbonate precipitating systems, such as the travertine formations in geothermal hot springs and stalactite formations in limestone caves. Detailed information about the research group I am working with is available on this page, and details of the individual projects I have been working on is available in my summary of research experience and on the following pages: 1. Geophysical pattern formation in carbonate precipitating systems 2. Scaling behaviors of Griffiths ferromagnets 3. Non-equilibrium dynamics in pure materials and binary alloys Publications 1.

He enrolled in the undergraduate program in the Department of Physics at the Chinese University of Hong Kong in 2000. In the summer of 2002, he was an exchange research assistant in the California Institute of Technology. After receiving his B.S. in Physics in 2003, he entered the graduate program in the Department of Physics at the University of Illinois at Urbana-Champaign and joined Nigel Goldenfeld’s research group. He is expecting to obtain his doctoral degree in September 2007. Links ¨ Nigel Goldenfeld’s research group ¨ Bruce Fouke’s research group Last update: 21 June, 2007 |
