Dr. Ashish Doshi is a pediatric cardiologist specializing in advanced cardiac imaging at Johns Hopkins Children’s Center in Baltimore, Maryland.Dr. Doshi completed a combined M.D./Ph.D. program at Duke University School of Medicine. His doctoral research was in the field of biomedical engineering, specifically computational modeling of cardiac electrophysiology. He completed his pediatrics residency at St. Louis Children’s Hospital, followed by a fellowship in pediatric cardiology at Children’s National Hospital in Washington, DC. During his cardiology fellowship, Dr. Doshi conducted research at The Johns Hopkins University School of Engineering. After finishing fellowship, he continued this work through a research fellowship funded by the American Heart Association, investigating MRI-based computational models for arrhythmia risk prediction in tetralogy of Fallot and pediatric myocarditis. He subsequently completed training in advanced cardiac imaging at Johns Hopkins Children’s Center.Dr. Doshi’s research interests involve the use of computational methods, particularly image-based biomedical modeling and computer simulation, for risk stratification and clinical decision support in children with congenital and acquired heart disease, with particular interests in hypertrophic cardiomyopathy, repaired tetralogy of Fallot, and single-ventricle disease. He has also conducted work in fetal electrocardiography and the use of cardiac MRI native T1 mapping for detection of heart transplant rejection.

Samuel C. Yiu, M.D., Ph.D., is an associate professor of ophthalmology at the Wilmer Eye Institute, specializing in cornea and external eye diseases, cataracts and refractive surgery (LASIK). In addition, he is a nationally and internationally recognized specialist in ocular surface diseases and ocular surface reconstruction surgery.Dr. Yiu received his M.Sc. (applied biometry) and Ph.D. (physiology and biophysics) from the University of Southern California. He then completed a post-doctoral fellowship in lacrimal physiology at the Schepens Eye Institute at Harvard Medical School and went on to earn his M.D. from the University of Alberta in Canada. Dr. Yiu completed an internship and his ophthalmology residency at Dalhousie University in Halifax, Nova Scotia and a fellowship in cornea, external disease and refractive surgery at the University of Southern California’s Doheny Eye Institute. After serving as the director of Doheny’s Ocular Surface Center and co-director of Doheny’s cornea division, Dr. Yiu joined the Wilmer faculty in 2011 and spent two years as the chief of the cornea division at King Khaled Eye Specialist Hospital (KKESH), Wilmer’s affiliate hospital in Riyadh, Saudi Arabia, before returning to Baltimore in 2013.

Marianne Cowley, M.D., is a clinical associate of ophthalmology and retina specialist at the Wilmer Eye Institute's Green Spring Station and Odenton, Maryland locations. Dr. Cowley specializes in the diagnosis and treatment of conditions such as age-related macular degeneration (dry and wet) and diabetic retinopathy. Dr. Cowley comes from private practice where she has focused on clinical excellence and patient experience in retinal care. For many years, Dr. Cowley volunteered her services with the University of Louisville and has made trips internationally to assist in providing retinal care.
