Dr. Jeanne Sheffield is the director of the Division of Maternal-Fetal Medicine and a professor in the Johns Hopkins Medicine Department of Gynecology and Obstetrics. Her areas of clinical and research expertise include medical and surgical complications of pregnancy with a focus on infectious diseases and immunizations in pregnancy. Dr. Sheffield earned her undergraduate degree from the University of Notre Dame and her medical degree from the University of Alabama at Birmingham. She did her residency in obstetrics and gynecology there, and then completed a maternal-fetal medicine fellowship at the University of Texas Southwestern Medical Center in Dallas. She joined the Johns Hopkins faculty in 2015. Dr. Sheffield serves on a number of national boards and committees. She is a member of the American College of Obstetrics and Gynecology, Alpha Omega Alpha, the American Gynecologic and Obstetrics Society, the Society of Maternal-Fetal Medicine, and the Infectious Disease Society of Obstetrics and Gynecology. She is currently on the board of directors for the Society of Maternal-Fetal Medicine and serves on the Maternal-Fetal Medicine Division of the American Board of Obstetrics and Gynecology. She works with the National Institutes of Health on national grant reviews and safety monitoring boards, and has served on several working groups focusing on improving the pregnancy research infrastructure. She acts as a pregnancy consultant to the Centers for Disease Control and Prevention and is an active member of the National Vaccine Advisory Committee. Dr. Sheffield has published many articles in obstetrics and maternal-fetal medicine journals, and written numerous textbook chapters. She is currently an editor of Williams Obstetrics, the definitive obstetrics textbook used worldwide. She is a journal reviewer for a number of peer-reviewed journals in her specialty.

Henry D. Jampel, M.D., M.H.S., is the Odd Fellows Professor of Ophthalmology at the Wilmer Eye Institute. He specializes in glaucoma and serves as the medical director of Wilmer's Green Spring Station location. His research interests include evaluation of medical vs. surgical treatment of glaucoma in newly diagnosed patients and on imaging devices for the detection of glaucoma and its progression.Dr. Jampel received his M.D. degree from Yale University and his M.H.S. in health finance and management from the Johns Hopkins Bloomberg School of Public Health. He completed an internship in internal medicine at Sinai Hospital and his residency in ophthalmology at the Wilmer Eye Institute. After completing a glaucoma fellowship in glaucoma at Wilmer, Dr. Jampel joined the faculty in 1988.

Sezen Karakus, M.D., is an assistant professor of ophthalmology specializing in corneal and external eye diseases, with a particular focus on ocular surface conditions in patients with autoimmune and inflammatory disorders such as Sjögren's syndrome and ocular rosacea. Her expertise also extends to corneal diseases involving abnormal sensory nerves, such as neurotrophic keratitis and neuropathic corneal pain. She is skilled in performing routine and complex procedures, including cataract and intraocular lens surgeries, refractive surgeries, corneal transplants, ocular surface reconstructions and amniotic membrane transplantations.At the Wilmer Eye Institute, Johns Hopkins Medicine's Ocular Surface Diseases and Dry Eye Clinic, she plays an integral role as a team member, providing her clinical insights and expertise. Additionally, she serves as an ophthalmologist in the Postural Orthostatic Tachycardia Syndrome (POTS) program at Hopkins. This unique position allows her to address dysautonomia-related neuropathic eye pain and ocular surface diseases in patients with POTS, combining her eye specialization with a focus on this specific medical condition. As a clinician-scientist, her research revolves around ocular surface diseases. Dr. Karakus is actively investigating the role of the ocular surface microbiome in the pathogenesis of ocular rosacea. Her involvement in the NIH U24 Ocular Surface Microbiome Consortium allows her to collaborate with fellow experts in the field to standardize research methrods and develop validated protocols for studying the ocular surface microbiome.Another area of research interest for Dr. Karakus involves serological and tear biomarkers in Sjögren's disease. Through a longitudinal study, she aims to determine the utility of tissue-specific autoantibodies for early diagnosis of Sjögren's disease in patients with dry eyes. Understanding the broader impact of Sjögren's disease on the peripheral and central nervous systems is crucial, as it can manifest as severe ocular surface disease with diminished corneal sensation (neurotrophic keratitis) or intense eye pain without significant ocular surface disease (neuropathic corneal pain). Her clinical expertise and research contributions have earned Dr. Karakus recognition regionally and nationally, as evidenced by her role as a consultant in complex dry eye and ocular surface diseases. She takes pride in her dedication to advancing the understanding of ocular surface conditions and providing the best possible care for patients. By combining her specialization in corneal and external eye disease with her involvement in the POTS program and cutting-edge research on ocular surface diseases, Dr. Karakus strives to make a significant impact on patient care and contribute to the advancement of ophthalmology and related fields.
