Professor Wang's research and teaching interests are principally in the area of biochemical engineering. He has published 5 books and over 200 technical articles in journals, and is widely regarded as one of the leaders in his field. His most recent research interests include studies of the use of reaction network modeling of animal cell metabolism to improve therapeutic protein production in bioreactors. He has also recently been interested in characterizing the heterogeneity of glycosylated proteins using mass spectroscopy and related bioanalytical methods, and in controlling the structure of the glycan moieties of glycosylated proteins during the production of proteinaceous drugs.

Professor Wang is on the editorial boards of 12 journals in the biotechnology field, including Biotechnology and Bioengineering (where he is editor-in-chief), Advances in Biotechnology, Biotechnology and Bioprocess Journal, and Applied and Environmental Biotechnology. He is a member of the National Academy of Engineering and the American Academy of Arts of Sciences, and a Founding Fellow of the American Institute of Medical and Biological Engineering. He is also a recipient of the M. J. Johnson Award from the American Chemical Society, the Asia-Pacific Distinguished Biochemical Engineering Award, and the William H. Walker Award and the Food, Pharmaceutical and Bioengineering Award from the American Institute of Chemical Engineers.
