    Dr. Schafer is Professor of Medicine and of Epidemiology & Biostatistics at UCSF and Chief of Endocrinology and Metabolism 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 osteoporosis treatment and the assessment of response to osteoporosis therapy. She also studies the relationships between bone, fat, and glucose metabolism, including the effects of obesity and diabetes on bone, and the skeletal regulation of energy metabolism. This research program includes investigations of the effects of bariatric surgery (weight loss surgery) on calcium metabolism and skeletal health. Dr. Schafer's research has been funded by the National Institutes of Health, the US Department of Veterans Affairs, and the American Society for Bone and Mineral Research.
