Dr. Clines has been studying and thinking about bone diseases for nearly 30 years. His basic science laboratory studies how novel factors such as hypoxia, androgens, endothelins, Wnt signaling, and other factors regulate the osteoblast-cancer cell synergy in bone metastasis. His other research interests include understanding how sex steroids regulate skeletal size and shape and the development of novel imaging techniques to assess bone quality.

His clinical interests include metabolic and genetic bone diseases as well as general endocrinology. Dr. Clines sees patients at the Metabolism, Endocrinology & Diabetes Clinic (Metabolic Bone Disease Clinic) and at the Ann Arbor Veterans Affairs Medical Center.
