  • 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 in by the American Board of Internal Medicine in Internal Medicine and by the American Board of Internal Medicine in Endocrinology, Diabetes and Metabolism Subspecialty.

Her research focus is on osteoporosis and metabolic bone disease. One of her specific research emphases is osteoporosis treatment and the assessment of response to osteoporosis therapy. Pharmacologic treatment for osteoporosis may involve the use of an antiresorptive agent (one that decreases bone resorption) or an anabolic agent (one that stimulates bone formation). Dr. Schafer and colleagues conducted a randomized, placebo-controlled trial testing two innovative combinations of concurrent and sequential anabolic and anti-resorptive therapy in postmenopausal women with low bone mass. Findings from the trial may help to expand treatment options for osteoporosis. Additionally, Dr. Schafer is actively engaged in research involving the relationship between bone and fat. Bone-fat interplay—including the effects of fat on bone metabolism and the skeletal regulation of energy metabolism—is an area of increasing investigation. Currently, she is studying the effects of bariatric surgery (surgical weight loss) on calcium metabolism and skeletal health. Her research is funded by the U.S. Department of Veterans Affairs, the National Institutes of Health (National Institute on Diabetes and Digestive and Kidney Diseases), and the American Society for Bone and Mineral Research.
