Appointment of Olga C. Aroniadis, M.D., to Chief, Division of Gastroenterology and Hepatology

The Department of Medicine is thrilled to announce the appointment of Olga C. Aroniadis, MD, MSc, FACG as the next Chief of Division of Gastroenterology and Hepatology.

Dr. Aroniadis is presently Associate Professor of Medicine, Director of Clinical Research in the GI division, Director of Master of Science in Epidemiology and Clinical Research Program in the School of Public Health, and Director of the Women’s Health Center for Gastroenterological Diseases and Disorders at Stony Brook Medicine.

Having arrived in Stony Brook as a faculty member, Olga has already made numerous contributions to the trifecta missions of the institution: research, education, and patient care.  One of the focuses of her research efforts is to understand the roles of gut microbiome in the pathogenesis of GI diseases, and how the findings can be translated into treatment. More recently, Olga co-authored several papers that described the relationship between COVID-19 infection and GI symptoms and sits on the steering committee for the North American Alliance for the Study of Digestive Manifestations of COVID-19 (NAADMC).  Moreover, Dr. Aroniadis is part of a leadership team in Stony Brook’s pending application for a Clinical and Translational Science Award (CTSA) from the National Institutes of Health, serving as a co-investigator of the KL2 component of the grant.

In education, Olga is actively engaged in numerous teaching and training activities at the levels of medical students, graduate students, residents, and fellows.  She is particularly focused on the teaching evidence-based-medicine (SBM) in disease management to students and trainees. She is also recognized as an educator in national professional societies, having served or is serving, for example, on the Research Committee, Training Committee and Educational Committee of the American College of Gastroenterology (ACG).

Finally, as an astute clinician, Dr. Aroniadis is passionate about patient care, especially in women’s health, having recently founded a multidisciplinary center at Stony Brook to provide care to women with GI diseases and disorders.

Born in Brooklyn and raised in Long Island, Dr. Aroniadis received her M.D. degree with Research Distinction in Gastroenterology from the Albert Einstein College of Medicine, where she was also granted a M.Sc. degree in Clinical Research Methods. She conducted residency training in Internal Medicine, and was Chief Resident, at the Montefiore Medical Center, where she also received fellowship training in Gastroenterology.  After several years as a faculty member at Albert Einstein College of Medicine Montefiore, Dr. Aroniadis joined Stony Brook in 2019.

Given what she has accomplished in the very short duration at Stony Brook, we are fully confident that Dr. Aroniadis will be a strong leader and advocate for the Division of Gastroenterology & Hepatology.  The division will be in good hands under her stewardship, and we look forward to working with her to build an even stronger GI group.

Please join us in congratulating Dr. Aroniadis in her new position as we wish her continued success in her future endeavors, and throughout her Stony Brook career.
