Graduated from HKU (Undergraduate) and Northwestern University (PhD), I am a theoretical condensed matter physics interested at application of Quantum Field Theory to condensed matter systems. Topics of research interests include strong correlated electrons and spin-liquid states, non-equilibrium mesoscopic transports, topological order and unconventional superconductors. Since 2000/2002, I am a Fellow of the American Physical Society (2000) and a Croucher Senior Research Fellow (2002).
I am also deeply involved in promoting Science education and education for the gifted learners. I am a member of CDC Committee on Science Education, CDC since 2002 and a member of CDC Committee on Gifted Education, CDC since 2012. At present I am a Co-Editor of Europhysics Letters and a Council Member of the Hong Kong Institute of Education (HKIEd). I am taking a no-pay leave from my professorship to be the Executive Director of the Hong Kong Academy of Gifted Education starting June 1st, 2014.
