Wen Xie (MD, PhD) is Chairman of the Department of Pharmaceutical Sciences, and Joseph Koslow Endowed Professor in Pharmaceutical Sciences at the School of Pharmacy, and Professor of Pharmacology & Chemical Biology at the School of Medicine.

Dr. Xie obtained his MD degree from Peking University Health Science Center, and PhD in Cell Biology from University of Alabama at Birmingham. He completed a postdoctoral fellowship with Dr. Ronald M. Evans at the Salk Institute in La Jolla, California before joining the University of Pittsburgh.

The research focus of Dr. Xie's laboratory is nuclear receptor-mediated transcriptional regulation of genes that encode drug metabolizing enzymes and drug transporters. In addition to metabolizing drugs, the same enzyme and transporter systems are also responsible for the homeostasis of numerous endobiotic molecules. Therefore, besides drug metabolism and disposition, this regulation has broad implications in many human diseases, including liver diseases (fatty liver, liver fibrosis, liver cancer, and autoimmune hepatitis), endocrine disorders, metabolic syndrome, and cancers. Dr. Xie’s research is conducted using a combination of cell cultures and genetically engineered mice that include tissue and cell type-specific transgenic, knockout and humanized mice.

Dr. Xie is the author or coauthor of nearly 190 journal articles and book chapters and he has delivered over 190 invited lectures at conferences and universities. Dr. Xie has edited two books: "Nuclear Receptors in Drug Metabolism", a book published by Wiley in 2008 and "Drug Metabolism in Diseases", an Elsevier book published in 2016. Dr. Xie has served as ad hoc reviewer for NIH and DOD Study Sections and for over 90 scientific journals.

Among his achievements, Dr. Xie is the recipient of the University of Pittsburgh Chancellor’s Distinguished Research Award, the James R. Gillette International Society for the Study of Xenobiotics (ISSX) North American New Investigator Award, the American Society for Pharmacology and Experimental Therapeutics (ASPET) Division for Drug Metabolism Early Career Achievement Award, and the Joseph Koslow Endowed Chair in Pharmaceutical Sciences.
