About the Key Opinion Leaders

Eliza B. Geer, MD, is the Medical Director of Memorial Sloan Kettering’s Multidisciplinary Pituitary & Skull Base Tumor Center and Professor of Medicine and Neurosurgery. She is an endocrinologist who specializes in caring for people with pituitary and neuroendocrine diseases. She completed her internship and residency at the New York-Presbyterian Hospital/Columbia Medical Center, and fellowship in endocrinology and metabolism at the Icahn School of Medicine/Mount Sinai Medical Center. She is involved in clinical trials investigating new medical therapies for patients with Cushing’s, acromegaly, and prolactinoma. Her current research interests focus on characterizing patient reported outcomes in patients with Cushing’s and acromegaly, and treatment of aggressive pituitary tumors.

Antonio C. Bianco, MD, PhD, is a physician-scientist who has made influential contributions to the field of thyroid diseases and an enduring commitment to education and mentorship. He joined the University of Texas Medical Branch in September 2024 and currently serves as interim Senior Vice President and Dean of the John Sealy School of Medicine, and Chief Research Officer. Dr. Bianco earned his MD at the Santa Casa Medical School and PhD in human physiology at the University of São Paulo, both in São Paulo, Brazil. His career includes faculty and leadership appointments at Brigham and Women’s Hospital in Boston, the University of Miami, Rush University, and the University of Chicago. Dr. Bianco has published extensively in the area of thyroid hormone metabolism and action. His findings have significant clinical implications and have shaped the treatment of millions of patients with hypothyroidism. His research career has focused on how T3 (triiodothyronine) initiates or terminates critical biological steps while maintaining relatively stable plasma levels. Most recently, his laboratory has focused on the epigenetic mechanisms of T3 action and their implication for children with congenital hypothyroidism. He has been recognized with numerous awards from national and international professional associations, and membership in the American Society for Clinical Investigation and the Association of American Physicians. He served as a regular member of NIH study sections for almost 10 years, and the Board of Scientific Counselors of the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK).

Dr. Celi has completed his clinical fellowship in Endocrinology, at the University of Maryland in Baltimore. He was awarded the Masters in Health Sciences by Duke University. Dr. Celi conducts clinical and translational research and his scientific interest is focused on the physiology and pathophysiology of thyroid hormone action as it relates to energy metabolism. Dr. Celi served as Principal Investigator of several clinical trials on innovative treatments for hypothyroidism. Another area of research is in the mechanisms of adipose tissue differentiation and on the role of hormonal signaling on promoting differentiation of adipose tissue depots in thermogenic fat, able to dissipate energy. Dr. Celi is a practicing endocrinologist, and his clinical interests are diabetes and thyroid disease, with a specific focus on thyroid hormone replacement therapy, imaging, fine needle aspiration biopsy, and multidisciplinary management of thyroid cancer. During his tenure at VCU Dr. Celi has worked on innovative care delivery models for patients with diabetes including creating an inpatient diabetes management team, testing the use of continuous glucose monitoring for patents admitted with COVID-19, developing a protected discharge service with remote home monitoring, and instituting a pre-surgical diabetes optimization.
