Tiffany Kim, MD

Assistant Adjunct Professor

Dr. Kim is Assistant Professor of Medicine at UCSF and Staff Physician at the San Francisco VA Health Care System. She is board-certified by the American Board of Internal Medicine in the subspecialty of Endocrinology, Diabetes and Metabolism. Her research focus is osteoporosis and bone metabolism. One of her research emphases is studying the relationships between bone, fat, and glucose metabolism. Currently, she is investigating the effects of improved glycemic control on bone marrow fat and skeletal health in people with type 2 diabetes. Dr. Kim's research has been funded by the US Department of Veterans Affairs, and the Endocrine Fellows Foundation.
