  • Director, Neuroendocrinology Unit
Academic Interests

Dr. Fazeli is a clinical/translational researcher with a primary interest in understanding both the benefits and negative consequences of undernutrition. Her research program has focused primarily on studying women with anorexia nervosa and the hormonal adaptations that lead to profound bone loss in this population. She has performed clinical studies investigating therapies for the treatment of bone loss in women with anorexia nervosa and is currently investigating the effects of transdermal estrogen through an NIH-funded protocol. Dr. Fazeli’s research has also focused on understanding the pathophysiology of bone loss in chronic undernutrition and the potential role and function of bone marrow adipose tissue, a fat depot which is paradoxically increased in states of starvation. Dr. Fazeli has a clinical interest in understanding the hormonal determinants of amenorrhea and infertility and has used large database methods to answer clinically relevant questions in this field.

Dr. Fazeli has mentored students, residents and fellows interested in neuroendocrinology/endocrinology. She previously served as an Associate Program Director for the Endocrine Division Fellowship Program at the Massachusetts General Hospital and also served as a Director for the Reintroduction to Clinical Medicine course for MD/PhD students at Harvard Medical School.
