Katherine Yun, MD, received her medical degree from Harvard Medical School in 2006 and completed her residency in pediatrics at Yale University in 2009. Between 2009-2011, she was a Robert Wood Johnson Foundation Clinical Scholar and earned her Master’s in Health Sciences Research from Yale University. While at Yale, she was the supervising physician in the Yale-New Haven Hospital Pediatric Refugee Clinic, a co-recipient of Connecticut’s Myra M. Oliver Award for going “above the call of duty” to help refugees and immigrants.

Dr. Yun is currently an Assistant Professor of Pediatrics at the University of Pennsylvania School of Medicine and an attending physician in the Division of General Pediatrics and the Refugee Health Program at Children’s Hospital of Philadelphia. Her primary interest is refugee and immigrant health, specifically the well-being of children in immigrant families in the United States. Her work has focused on access to care for children and families with limited English proficiency, community-based healthcare navigation, the prevalence of non-communicable conditions and insurance coverage among refugees in the U.S., and the use of clinical decision support to promote evidence-based, guideline-directed immigrant healthcare. She is concerned with equity in access to healthcare, documenting the impact of health policies on immigrant children and families, and training the next generation of pediatricians on multilingual child health research and practice.
