Brief Resume

Following graduation from Creighton University School of Medicine, Dr. Aloia completed a residency in Internal Medicine and was an officer in the U.S. Army. He completed fellowship training in Diabetes and Metabolism at Jefferson Medical College and is board certified in Internal Medicine and Endocrinology. After completion of his fellowship he joined the staff at Meadowbrook Hospital (now NUMC) where he became Director of the Metabolism unit and eventually acting Chair of Medicine. During the decade at NUMC he was a research collaborator at Brookhaven National Laboratory. His collaboration with Stanton Cohn, Ph.D. led to seminar papers describing bone mass in health and various diseases, as well as other disorders of calcium metabolism. In 1978 he became Chairman of Medicine at Winthrop-University Hospital, Chief Academic Officer and Associate Dean at Stony Brook. He established the Bone Mineral Research Center which has had multiple NIH and other investigator-initiated grants and participated in almost every pharmaceutical trial for the prevention or treatment of osteoporosis in the past 30 years. He has published over 160 articles and book chapters. He is nationally recognized as an expert on osteoporosis and related disorders.

Description of Research Interests/Activities

At Brookhaven National Laboratory, Dr. Aloia used in vivo neutron activation analysis and whole body counting to develop a model of body composition in aging. These studies led to the description of differences in the calcium economy and body composition between black and white women. He established the Bone Mineral Research Center at Winthrop-University Hospital. Several NIH grants supported research into the effects of calcium and estrogen on bone mass and the elucidation of body composition in black and white women. More recently, he showed that vitamin D supplementation did not slow bone loss in black women. His latest NIH grant is for a trial of vitamin D in elderly black women.

Areas of Experience

Research Team Members

The Bone Mineral Research Center is staffed by an Associate Director, Study Coordinator, Densitometry Technician,and Director of the Metabolism Lab.

Associate Director, Mageda Mikhail, MD

Jane Greensher, R.N.. MA, CCRC , Study Coordinator, manages and coordinates the clinical trial program for the Bone Mineral Research Center. She also designs and facilitates osteoporosis education programs for teens, peri-menopausal and post-menopausal women on the Center's behalf. At Winthrop since 1983, Ms. Greensher has played an integral role in managing a number of women's health, community outreach and patient counseling programs.

Sharon Sprintz, BSRT, LRT, CBDT, radiologic technologist who performs the Center's bone density testing. She works closely with the Center's medical staff on original research and has published three articles in professional journals about the effects of exercise on bone mineral content and density.
