Research Interest

The primary focus of my lab is to use an interdisciplinary approach to study natural product drugs. We are interested in studying three aspects of natural product drug discovery: 1) development of heterologous hosts for natural product production 2) discovery of natural products and their biosynthesis pathways in fungal and bacterial genomes 3) investigation in the production of drugs onboard the International Space Station. The long term goal of our Space project is to facilitate Human Space Exploration by providing the necessary drug production capabilities in outer space.

Biography

Dr. Clay Wang is a Professor at the USC School of Pharmacy, and the Chair of the Department of Pharmacology and Pharmaceutical Sciences. He also holds a joint appointment in the Department of Chemistry of the Dornsife College of Letters, Arts and Sciences and serves on the executive board of the USC Academic Senate.

Dr. Wang received his B.A. in chemistry from Harvard University in 1996 and a Ph.D in chemistry from the California Institute of Technology in 2001. After completing a two- year, postdoctoral fellowship in chemistry and chemical engineering at Stanford University, he joined the faculty in the Department of Pharmaceutical Sciences at USC School of Pharmacy as an Assistant Professor in 2003.

His research program focuses on the interface of chemistry and biological sciences. Specifically he is exploring the mechanism of natural product biosynthesis in bacteria and fungi. His lab has been studying the use of Aspergillus nidulans as a general host for the production of fungal natural products. The lab is supported from a variety of sources including National Institute of Allergy and Infectious Diseases (NIAID), National Institute of General Medicine (NIGMS), American Cancer Society, National Science Foundation (NSF), Department of Energy (DOE), Department of Defense (DOD), Joint Genome Institute (JGI), NASA, and ISS-CASIS.
