Youngjin Cho, MS, PhD

Research interests

Youngjin Cho, MS, PhD, is associate professor of immunology in the Department of Medical Education. She received her bachelor of science and master of science degrees from the Korean Advanced Institute of Science and Technology, South Korea, and her PhD in pathobiology at Keck School of Medicine at University of Southern California in affiliation with Children Hospital of Los Angeles. She worked as a postdoctoral fellow at Children Hospital of Los Angeles, Marry Babb Randolph Cancer Center at West Virginia University and Geisinger Commonwealth School of Medicine.

With the growth of Geisinger Commonwealth, Dr. Cho transitioned from a biomedical researcher, conducting a research related to breast cancer and mesenchymal stem cells utilizing mouse model, to a medical educator. She has been co-directing medical science courses for pre-clerkship students and overseeing the immunology content delivery throughout the curriculum. She completed an International Association of Medical Science Educator (IAMSE) fellowship. Since 2019, she has been the immunology lead on the editorial board of Aquifer Science™, an organization to develop and disseminate teaching and learning tools that promote cognitive integration and collaborative teaching of basic and clinical sciences in health profession education.

Dr. Cho's educational research focuses on effective instructional approaches in medical education. She was funded to develop a curriculum to enhance medical student training toward people with intellectual disabilities and has led several funded educational research projects.
