Eliza B. Geer, MD joined the faculty at The Mount Sinai Medical Center in July, 2006 with an appointment in the Division of Endocrinology and a secondary appointment in the Department of Neurosurgery. After graduating from Columbia University, she attended Mount Sinai School of Medicine, graduating in 2000 with Distinction in Research. She completed her Internship and Residency in Internal Medicine at Columbia Presbyterian Medical Center, where she became involved in neuroendocrine research., conducting studies on the hypothalamic-pituitary-adrenal-axis and acromegaly. After completing her Residency in 2003, she conducted a year of clinical research at Columbia's Obesity Research Center, funded by a NIH T32 grant, where she focused on body composition and appetite in acromegaly. She then completed a fellowship in Endocrinology, Diabetes and Bone Disease at the Mount Sinai Medical Center, graduating in 2006.

Her clinical and research interests include pituitary diseases and neuroendocrinology, and she sees pituitary patients with Dr. Kalmon Post in the faculty practice. She is the principal investigator of a study investigating body composition and appetite in Cushing's Disease patients before and after transsphenoidal surgery; this study is funded by a NIH K23 award. She is also involved in studies investigating bone loss in Cushing's Disease and the prevalence of cardiac valvulopathies in hyperprolactinemic patients treated with chronic cabergoline.
