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

Wang uses protein mass spectrometry (MS) as the primary tool to develop analytical techniques and instruments for analysis of protein complexes, protein higher-order structure and protein therapeutics, with emphasis on (1) biological functions of macromolecular assemblies; (2) protein denaturation and aggregation; (3) post-translational modification and stability of protein therapeutics, and their impact on efficacy and safety. He developed 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 immunoreactions and protein denaturation/aggregation, efficacy and stability of protein therapeutics, etc.. Wang has published articles with first- or corresponding authorship in journals including PNAS, Mol. Cell, Anal. Chem. and mAbs, one book translation and multiple book chapters. He was granted one U.S. patent on his intention of MS ion source used for accessing protein stability. Wang is currently serving in the Editorial Advisory Board of Cambridge Scholars Publishing and Editorial Board of a peer-reviewed journal Analytical Instrumentation.
