Wei Xin, MD, PhD

Associate Professor
Department of Pathology
School of Medicine

Dr. Xin graduated from Shanghai Medical University (1991) and finished his urology residency in Shanghai First People's hospital. Then he came to USA to study molecular mechanism of hepatitis B virus and subsequently received a PhD from the State University of New York at Buffalo (1998).

He received his AP/CP pathology training in University of Michigan, Ann Arbor, as well as completed his fellowship training of surgical pathology with subspecialty of GI/liver pathology. In addition, he received pancreatic pathology training in GI/liver division of Johns Hopkins University and received the Rodger C. Haggitt GI Pathology Society award for best resident presentation (2003), and M.R. Abell House Officer Award for the outstanding and exemplary achievement in the discipline of pathology (2004).

Before joining the faculty as assistant professor at Case Western Reserve University, Dr. Xin was the faculty of the Department of Pathology as lecturer in University of Michigan and served as the GI pathologist and associated medical director of Acupath Laboratory Inc (Plainview, NY).

Currently,  Dr. Xin is an associate professor and the director of autopsy, specializing in GI/liver pathology. His research has been on GI tract carcinogenesis with mice model and translational research, with publications in dozens of prestigious journals.
