                                1996-1998  Assistant Professor, Institute of Biophysics, CAS

                                1998-2000  Associate Professor, Institute of Biophysics, CAS Visiting Scientist in the Institute of Food Research, Norwich, UK (The Royal Society K.C. Wong Research Fellowship)

                                2000- Principle Investigator (PI) (2004, full professor. Institute of Biophysics, CAS. 2004-2005,Visiting Scientist, Center for Cancer Research, the Medical Research Council, Cambridge, UK)

                                Research area: Redox, Aging, Traditional Chinese medicine (Nitric oxide and S-nitros(yl)ation and other thiol modification in cellular quality control; redox regulation in aging and the related diseases; mechanism of traditional Chinese medicine). Chen laboratory discovered the important roles of S-nitrosation in protein trafficking, post-translational modification, aging-related cognitive impairment and diseases such as atherosclerosis. They also developed a series of methods for S-nitrosation detection. Their work well demonstrated the specificity and the important signaling roles of redox regulation. She proposed the concept of Precision Redox and Redox-stress Response Capacity (RRC) and has demonstrated the significance of the decay of RRC in aging.

                                She has been honored National Outstanding Young Scientists and also a receiver of Special Government Allowances of the State Council. She is the Chief Scientist of “National Basic Research Program of China, 973 Program” (2006-2010) and the Chief Scientist of “National Key Research and Development Program of China” (2017-2022). Dr. Chen also serves on the editorial board of Free Radical Research and Redox Biology and the Associate Editor of Free Radical Biology & Medicine.
