Background

Doctor of Philosophy (Condensed Matter Physics), Nanjing University, Nanjing, China 09/1994 – 07/1997
Bachelor of Science (Honours) (Condensed Matter Physics), Nanjing University, Nanjing, China 09/1988 – 07/1992

Achievements

Applied atomistic modelling techniques to support research projects within NFC, developed the capability of atomistic simulation on the behaviour of nuclear materials under high temperature, radiation damage and mechanical deformation. Initiated atomistic simulations on Accident Tolerant Fuel materials: thermal properties of SiC and U-Si systems.
Developed the capability for ANSTO to participate in international comparison of pure beta and electron capture radionuclides through the successful TDCR system.
Research outcomes have been published in international scientific journals (more than 100 journal articles), and presented in international conferences
