He is now professor of both Tongji and SIBS, and also serves as the editor-in-chief of the international journals "Cell Research" and "Cell Discovery". His work has contributed to new insights into transmembrane cellular signaling through a variety of receptors (especially GPCRs) and their response to a variety of environmental stimuli. Currently he focuses on stem cell research of cell reprogramming by small molecules and underlying mechanisms of anti-Alzheimer disease and anti-aging approaches by natural products. He is a member of CAS elected in 1999 and of TWAS in 2001.
