Rex Ahima, M.D., Ph.D., Director
Dr. Ahima is Associate Professor of Medicine at the University of Pennsylvania. He received a BSc degree from the University of London, MD from the University of Ghana, PhD from Tulane University in New Orleans, Louisiana. After completing an internship and residency in internal medicine at the Albert Einstein College of Medicine, Jack D. Weiler Hospital and Jacobi Medical Center in New York, Dr. Ahima moved to the Beth Israel Deaconess Medical Center and Harvard Medical School in Boston, for subspecialty training in Endocrinology, Diabetes and Metabolism, and postdoctoral research in the laboratory of Dr. Jeffrey Flier.
Dr. Ahima served as Instructor in Medicine at Harvard prior to moving to Penn in 1999. He received the Owl Club, Leo Davidoff and Pfizer Awards at Tulane, Albert Einstein and Harvard. Dr. Ahima was elected to the American Society for Clinical Investigation in 2005, is a member of the Endocrine Society, American Diabetes Association, American Physiological Society, and Society for Neuroscience, and a reviewer for the National Institutes of Health, Wellcome Research Foundation of the United Kingdom, and Howard Hughes Medical Institute. Dr. Ahima is a member of the Institute of Neurological Sciences, and the Neuroscience, Cell Biology and Physiology and Pharmacology Graduate Groups at Penn. He is director of the Penn Diabetes and Endocrinology Research Center (DRC) Mouse Phenotyping, Physiology and Metabolism Core, which offers diagnostic testing in rodent models.
Dr. Ahima's research is focused on energy and glucose homeostasis. He is interested in how adipocyte hormones, such as leptin, adiponectin and resistin regulate appetite, metabolism and hormones. These studies which have important implications for obesity and diabetes, involve the use of transgenic mice, chemical and immunoassays, in vivo metabolic measurements, neurochemistry and tissue culture techniques. Dr. Ahima has a clinical interest in the neuroendocrinology of obesity and diabetes. He directs the Weight Management and Metabolism Clinic at the Presbyterian Medical Center, in collaboration with the Preventive Cardiology Program. Dr. Ahima is the director of the Obesity Unit of the University of Pennsylvania Institute for Diabetes, Obesity and Metabolism.
