Congratulations to the following Chobanian & Avedisian School of Medicine faculty on their recent appointment or promotion.

Clinical Professor

Christopher Merritt, MD, MPH, MHPE, Pediatrics, joins the community as chief of pediatric emergency medicine at Boston Medical Center. He received his MD and MPH degrees from Tulane University, completed his pediatrics residency at Children’s Memorial Hospital/Northwestern University and a fellowship in pediatric emergency medicine at Hasbro Children’s Hospital, Brown University. He subsequently earned a master’s in health professions education from the University of Michigan. Previously, he served as associate professor of emergency medicine and pediatrics at the Warren Alpert Medical School of Brown University and an attending pediatric emergency medicine physician at Hasbro Children’s Hospital in Providence, Rhode Island. While at Brown, he served briefly as residency director for pediatrics, was interim assistant dean for faculty development, chaired faculty development committees, directed the medical education fellowship at Brown EM and served on Brown EM’s board of directors.

Clinical Associate Professor

Stephanie Stapleton, MD, Emergency Medicine, focuses on translational simulation, procedural training/curriculum development in simulation-based education and developing an emergency medicine (EM) simulation research community, with special emphasis on procedural training, pediatric resuscitation and distance simulation. She has led national workgroups through the Society for Academic Emergency Medicine Simulation Academy, addressing gaps and standards in simulation procedural trainers and creating monetary awards for novice simulation researchers. As the department’s director of EM simulation, Dr. Stapleton has innovated and led a comprehensive four-year simulation curriculum for the EM residency program that combines procedural training and high-fidelity simulation, enabling residents to meet index procedure requirements and refine clinical reasoning. She also has created and iterated a comprehensive curriculum for faculty development and leads interdisciplinary in situ simulations on high-acuity, low-occurrence (HALO) events.

Christina Lam, MD, Dermatology, focuses her clinical and research interests around connective tissue diseases, such as cutaneous lupus, dermatomyositis and morphea, and complex medical dermatology, including sarcoidosis and vasculitis. Dr. Lam leads a subspecialty Rheumatologic Dermatology Clinic at Boston Medical Center, in which individualized and advanced therapies are coordinated for these challenging diseases. She also serves as chief and chair ad interim of the department and has been program director of the rheumatologic dermatology fellowship since 2021.

Nicholas Musisca, MD, MA, Emergency Medicine, joins the community as the emergency medicine (EM) residency program director at Boston Medical Center (BMC). He comes to BU-BMC from Wellstar/Medical College of Georgia at Augusta University where he served as residency program director for two years. He started his academic career as assistant professor of emergency medicine at Warren Alpert Medical School of Brown University and an attending EM physician at the Miriam and Rhode Island hospitals. His areas of focus encompass simulation-based education to include cadaver-based procedure labs, producing procedural videos and managing structured oral board preparation. He served as the lead instructor for airway management while at Brown EM and developed a multi-hospital in-situ mass casualty simulation.
