His primary clinical interests are endocrine diseases that affect bone and mineral metabolism, particularly osteoporosis, primary hyperparathyroidism, hypoparathyroidism, rickets and genetic bone disease. Dr. Levine has an active laboratory research program that complements and extends his clinical studies. He has identified the molecular basis of several inherited disorders of mineral metabolism. His research interests extend to the molecular basis for embryological development of the parathyroid glands.
