Researches

Chuan-Hui Zhang is a computational material science-worker who working in the fields of alloy, surface and interface systems. He received a PhD in condensed matter physics from University of Science and Technology Beijing (USTB) in 2013. Now he works at National Center for Materials Service Safety (NCMS) of USTB to be an associate professor. He is interested in the mechanism of metal surface/interface corrosion and the development of classic force-field, and do the simulation by first-principles, molecular dynamics and other atomic calculations.
