CLIFFORD J. ROSEN, M.D., is Senior Scientist at Maine Medical Center’s Research Institute. He is the Former Director of the Maine Center for Osteoporosis Research and Education, an affiliate of St. Joseph Hospital, a Center that he started more than 15 years ago. He previously conducted more than 15 NIH and pharmaceutical sponsored clinical research trials, and he currently oversees three investigator-initiated NIH-funded translational projects. He is Past President of the American Society of Bone and Mineral Research (ASBMR; 2002–2003), and he served 5 years as the first Editor in Chief of the Journal of Clinical Densitometry as well as Associate Editor of the Journal of Bone and Mineral Research. Dr. Rosen is the Editor in Chief of The Primer on the Metabolic Bone Diseases and Disorders of Mineral Metabolism, and is serving a 4-year term on The Advisory Council for the National Institutes of Arthritis Musculoskeletal and Skin Diseases and the FDA Endocrinologic and Metabolic Advisory Committee. He is also a member of several professional societies including the Endocrine Society, the American Society of Bone and Mineral Research, and the American Federation of Clinical Research. He is a Professor of Nutrition at the University of Maine and works as a Senior Staff Scientist at the Jackson Laboratory in Bar Harbor, Maine, studying insulin-like growth factors and skeletal remodeling in mice. His work includes more than 305 manuscripts in a variety of journals including Nature Medicine, the New England Journal of Medicine, and Proceedings of the National Academy of Sciences. Dr. Rosen received his medical degree from the State University of New York, Syracuse.
SUE A. SHAPSES, Ph.D., is Professor, Department of Nutritional Sciences at Rutgers University. Prior to this she was a Post-doctoral Research Fellow with the Department of Orthopedic Surgery/Division of Biochemistry at Columbia University. Her research focuses on nutritional aspects of calcium metabolism critical to normal growth and maintenance of skeletal tissue, with a focus on both the mineralized and extracellular matrix of bone in conditions of aging and disease states. An important aspect of her work addresses bone turnover and bone mass relative to how nutritional intake influences the development of osteoporosis. Calcium absorption (using stable isotopes) and bone-regulating hormones and cytokines are examined in her work so as to explore mechanisms of regulation. Dr. Shapses currently receives research support from the NIH in the area of the nutritional regulation of bone turnover, and also from Johnson & Johnson in the area of obesity prevention and treatment. She is a registered dietitian and board certified with the American Dietetic Association. Dr. Shapses received her Ph.D. from Columbia University.
