Jean-Pierre Raufman, MD

Dr. Raufman is board certified in Internal Medicine and Gastroenterology. A graduate of Albert Einstein College of Medicine, with postdoctoral training at the University of Michigan and the National Institutes of Health, Dr. Raufman has published more than 175 original research papers and more than 30 book chapters. He is an elected member of the American Society for Clinical Investigation, has chaired several NIH Study Sections and FDA Advisory Panels, and serves on the Editorial Board of the Jounal of Clinical Investigation. Since 2005, Dr. Raufman is PI on a unique University of Maryland/NIH GI and Liver Scholars Fellowship Trainiing Program and Program Director for an NIDDK T32 Training Grant, Training in Gastroenterology and Hepatology Research.

Dr. Raufman is a member of the Molecular and Structural Biology Program within the University of Maryland Marlene and Stewart Greenebaum Cancer Center Program in Oncology. As such, he collaborates with both basic and clinical research investigators to identify candidate proteins and genes that are relevant to muscarinic receptor signaling in colon cancer and may serve as markers for malignancy and therapeutic targets.

I completed GI Fellowship training at the University of Michigan where I worked in the lab of Dr. Jorge Gumucio (1978-80). I obtained three more years of research training at the National Institutes of Health in the NIDDK, Digestive Diseases Branch under the mentorship of Drs. Jerry D. Gardner and Robert T. Jensen (1980-83). Since July 1983, I maintain an independent research program whose unifying theme is the study of gastrointestinal regulatory molecules and signal transduction; I have been funded by R01, R21 and T32 awards from NIH (NIDDK and NCI), by the VA Merit program, and by foundations (e.g. AGA/Industry Award). I presented my work at prominent national meetings, secured patents, and published more than200 peer-reviewed research papers, reviews and book chapters (including 19 first- or senior-author scientific publications in the American Journal of Physiology, 10 in the Journal of Biological Chemistry, three each in Biochemical Pharmacology and Biomedical Biophysical Research Communications, two each in Cancer Research, Journal of Pharmacology and Experimental Therapeutics, Carcinogenesis, Molecular Cancer, and PLoS One, and one each in Proceedings of the National Academy of Sciences (USA), Experimental Cell Research, and the Biochemical Journal).
