Dr. Joy Wu is a board-certified endocrinologist with over 12 years' experience who specializes in treating women and men with osteoporosis and other bone and mineral diseases, including primary hyperparathyroidism, vitamin D deficiency, Paget's disease and fibrous dysplasia. She has a special interest in optimizing skeletal health for those at risk of bone loss from glucocorticoid treatment, cancer therapies, or organ transplant. She works closely with each individual and his/her referring physician to assess fracture risk, and to develop a tailored treatment and monitoring plan.

Dr. Wu directs a broad basic and translational research program that focuses on skeletal development and the bone marrow hematopoietic niche. Her laboratory is currently studying stem cell therapies for bone formation, and the prevention of cancer metastases to bone ( She has been honored with awards from the NIH Director’s New Innovator Award, the Endocrine Society, the American Society for Bone and Mineral Research, and the Mary Kay Foundation. Dr. Wu is committed to training the next generation of physician scientists, and serves as Co-Director of the Stanford Internal Medicine Translational Investigator Program.

Osteoporosis, a disease of fragile bones resulting in fractures, will strike 50% of women and 25% of men. As a physician scientist, Dr. Wu's laboratory is studying stem cells in the skeleton and bone marrow to develop novel regenerative approaches to increase bone quality and strength. They are also interested in how the skeleton supports hematopoiesis, and how diseases and medications that impact bone may affect blood cell production and cancer metastasis.
