Professional Background

2017-present Professor, School of Chemistry and Materials Science, Nanjing Normal University

2016-2017     Associate Professor, School of Chemistry and Materials Science, Nanjing Normal University

2013-2016     Researcher, Department of Chemistry, Utrecht University, and Netherlands Proteomics Centre

2008-2013     Ph.D., Department of Chemistry, University of Massachusetts Amherst, USA

2004-2008     B.S., College of Chemistry and Molecular Engineering, Peking University, China

We use protein mass spectrometry (MS) as the primary tool to develop biophysical/analytical techniques and instruments for analysis of natural proteins, protein complexes and protein therapeutics, with emphasis on (1) biological functions of macromolecular assemblies; (2) protein conformation and dynamics; (3) post-translational modification and stability of protein therapeutics. We develope innovative methods based-on strategies including native MS and hydrogen exchange MS to characterize protein structure, interaction and dynamics in detail, and applied these techniques to study mechanisms of biochemical reactions, protein denaturation/aggregation, and efficacy and stability of protein therapeutics, etc. 

Research Projects

We are currently conducting multiple projects under support of grants from NSFC, China Association for Science and Technology, and NJNU.
