Xiaoqiang Wang

Research Associate Professor

Xiaoqiang Wang, PhD. is Research Associate Professor in the Department of Biological Sciences. He received his Ph.D. in Structural Biology from the Institute of Biophysics, Chinese Academy of Sciences, Beijing, China in 1993. He worked as a research associate at the University of Manchester (UK, 1995-1996), and the Oklahoma Medical Research Foundation (1996-1999). He was a research fellow in the National Institute of Environmental Health Sciences (NIEHS)/National Institutes of Health (NIH) from 1999 to 2002. He was an Assistant Professor, Associate Professor and head of the structural biology laboratory in the Plant Biology Division, Samuel Roberts Noble Foundation from 2002 to 2014. His research interests include protein structure and design and engineering, plant natural products and biosynthesis, and enzyme-mediated drug metabolism and detoxification. He was awarded a federal grant by the National Science Foundation to study structure and function of glycosyltransferases involved in plant natural product biosynthesis, and was the first to solve the structure of a plant family I UDP-glycosyltransferase. He also obtained two NIH grants to engineer UGT71G1 for metabolizing an anticancer drug SN-38A. His research is providing a basis for understanding enzymatic mechanisms and biosynthetic processes towards manipulation of enzymes and biosynthetic pathways for improvement of plant, animal and human health. He has published original research articles in prestigious journals including Cell, Science, Molecular Cell, Plant Cell, Nature Structural Biology, and Proc. Natl. Acad. Sci. USA.
