Troy A. Markel, MD

Assistant Professor of Surgery

Bio

Troy Markel is a native of Pennsylvania and attended the University of Delaware for his undergraduate education. He obtained a B.A. in Biology and minored in chemistry and psychology. He then attended Penn State University College of Medicine in Hershey, Pennsylvania for his medical training. Following medical school, he attended Indiana University for his general surgery residency and pediatric surgery fellowship. He has an interest in basic science research and has a laboratory dedicated to stem cell biology and its applications for treating necrotizing enterocolitis. His clinical interests include neonatal surgery, short bowel syndrome, and extracorporeal circulatory support. Outside of medicine, he enjoys music and attending concerts at local music venues. He has played percussion for over 2o years and enjoys playing drums with his friends and family.
