Dr. Devin O'Brien Coon is a board-certified plastic and reconstructive surgeon at the Johns Hopkins University School of Medicine. He received his undergraduate and medical degrees from the University of Pittsburgh, where he graduated magna cum laude and received the Dean's Research Fellowship and Dean's Merit Scholarship. He also holds a master’s of science in engineering in bioengineering from the Johns Hopkins University Whiting School of Engineering and holds a second appointment as Associate Professor of Biomedical Engineering. He completed his general surgery and plastic surgery training at the Johns Hopkins University/University of Maryland program. His primary clinical interests include gender surgery, cosmetic surgery, facial trauma and complex surgical reconstruction including reconstructive microsurgery. He is also the medical director of the Johns Hopkins Center for Transgender Health, directs the surgical fellowship and leads a multidisciplinary program dedicated to providing comprehensive, affirming care across Johns Hopkins Medicine. He is frequently invited to lecture both nationally and internationally at conferences and as a visiting professor. He is a member of both the American Society of Plastic Surgeons and the Aesthetic Society and also serves on the editorial board of the Aesthetic Surgery Journal.

Dr. O’Brien Coon has published over 60 peer-reviewed publications and received numerous awards, including the BioMaryland LIFE (Leading Innovative Faculty Entrepreneurs) award. He is a two-time recipient of the D. Ralph Millard award from the Plastic Surgery Foundation for best scientific plastic surgery manuscript and was named a 2013 Innovator of the Year by the Maryland Daily Record. He directs a basic science research laboratory within the Translational Tissue Engineering Center that focuses on materials science, fibrosis and scarring in microtissue models and tissue engineering for surgical applications. He is one of a select group of physicians to have invented and developed medical devices (including a bioresorbable surgical implant and a 3-D ultrasound imaging system) through the entire development process from initial concept through to testing, FDA approval and clinical use. He is also an NIH-funded researcher whose inventions have led to numerous patents and a venture-backed startup company. more
