As an endocrine fellow at Jefferson Medical College, I spent much of my time carrying out research projects on diverse endocrine topics including acromegaly and diabetes insipidus. Those formative experiences with the creative aspects of scientific inquiry inspired me to pursue research throughout my career.

As a young attending physician practicing in the field of endocrinology, I began collaborating with Stanton H. Cohn, PhD, who was to become my mentor at Brookhaven National Laboratory. Dr. Cohn’s training in physics and math complemented my background in basic science and its application in clinical research. These research collaborations resulted in my lifelong interest in calcium metabolism.

Together, Dr. Cohn and I elucidated the effects of gender, race, and aging on the musculoskeletal system, and I continued to develop as an expert in osteoporosis and vitamin D—particularaly vitamin D in African Americans.

I have also contributed new knowledge about almost every known treatment for osteoporosis and was chosen to serve on the Institute of Medicine's Committee on Dietary Reference Intakes for Calcium and Vitamin D, an experience that solidified my expertise in this area.

After developing an interest in medical education, I became the acting Chairman of Medicine at Nassau University Medical Center. I was then recruited to become Chair of the Department of Medicine and Medical Education at Nassau Hospital, which is now NYU Langone Hospital—Long Island.
