Jennifer R. Marin, MD, MSc

  • Professor of Pediatrics, Emergency Medicine, and Radiology
  • Medical Director, Point-of-Care Ultrasound, UPMC Children's Hospital of Pittsburgh
  • Emergency Ultrasound Director, Division of Emergency Medicine

Jennifer Marin is professor of pediatrics, emergency medicine, and radiology at the University of Pittsburgh School of Medicine and faculty member in the Division of Emergency Medicine. She serves as the medical director for Point-of-Care Ultrasound at UPMC Children’s Hospital of Pittsburgh and director of emergency ultrasound for the Division of Emergency Medicine.

Marin completed a pediatrics residency at Ann and Robert H. Lurie Children's Hospital followed by a pediatric emergency medicine fellowship at the Children’s Hospital of Philadelphia during which time she also earned a Master of Science degree in Clinical Epidemiology. She subsequently spent an additional year learning point-of-care ultrasound in the Department of Emergency Medicine at the Hospital of the University of Pennsylvania.

One of the pioneers in pediatric point-of-care ultrasound, Marin has published extensively in the field and lectures and teaches internationally. Marin’s research focuses more widely on optimizing emergency diagnostic imaging, including utilization patterns and variations in care delivery. She has publications in several high impact journals and much of her work has garnered local and national media attention.
