Currently he leads a group to conduct fundamental studies on “Charge Transport in Mesoscopic Energy Conversion and Storage Systems”. He obtained his PhD of condensed matter physics at Institute of Physics, Chinese Academy of Sciences in 2002. Before joined NUS, he had been working with Prof. Michael Grätzel at Swiss Federal Institute of Technology (EPFL), and Dr. Arthur Frank at National Renewable Energy Laboratory (NREL) in the fields of nanostructured solar cells and lithium-ion batteries. He has authored over 60 peer-reviewed papers in international journals, and is the inventor of 8 patents in the fields of photoelectrochemical/electrochemical energy conversion and storage.
