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 the 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 methodologies in fields ranging from immunology to pharmaceutical research. Wang has published first-authored research articles in journals including PNAS, Mol. Cell and Anal. Chem., one book translation and multiple book chapters. Wang 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.
