    Collapse Overview
    Dr. Schafer is Assistant Professor of Medicine and of Epidemiology & Biostatistics at UCSF and a practicing endocrinologist at the San Francisco VA Medical Center. She is board-certified by the American Board of Internal Medicine in Internal Medicine and 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. Currently, she is investigating the effects of bariatric surgery (weight loss surgery) on calcium metabolism and skeletal health. Dr. Schafer's research has been funded by the NIH (National Institute of Diabetes and Digestive and Kidney Diseases), the US Department of Veterans Affairs, and the American Society for Bone and Mineral Research.
