Dr. Papaleontiou is an Assistant Professor of Internal Medicine with an appointment in the Division of Metabolism, Endocrinology and Diabetes at the University of Michigan. Prior to starting her internal medicine residency at Saint Peter’s University Hospital in New Jersey, she spent several years conducting clinical research on aging at Weill Cornell Medical College in New York City. She completed her endocrinology fellowship at the University of Michigan, where she subsequently joined the faculty. She is a recipient of Fulbright and Howard Hughes Medical Institute scholarships. Dr. Papaleontiou is a health services researcher in the field of thyroidology and aging. Her research focuses on evaluating the risks of thyroid hormone overtreatment and misuse in older adults, understanding the role of providers and patients in thyroid hormone use and misuse and how it relates to patient outcomes in the aging population, as well as the role of age and comorbidity in thyroid cancer decision-making. Her ultimate goal is to develop tools to tailor thyroid disease treatment to older adults by translating research findings into effective strategies and interventions to improve the care of older adults and reduce patient harm. Her research is currently supported by the National Institute on Aging, and she has also received funding from the Claude D. Pepper Older American Independence Centers, the University of Michigan Biology of Cardiovascular Aging Core, the Elizabeth Caroline Crosby Research Award and the U.S. Deprescribing Network. She serves on multiple national committees including as Co-Chair of the Annual Program Committee at the American Thyroid Association (2021-2022), Chair of the Ethics Committee at the North American Society for Interventional Thyroidology,  and Vice-Chair of the Thyroid Disease State Network at the American Association of Clinical Endocrinology. She is currently the President for the ATA’s Women in Thyroidology, Associate Editor for Endocrine Practice and Clinical Thyroidology, and serves on the Editorial Boards for Thyroid and BMC Endocrine Disorders.
