Bio: I am a recent arrival to graduate medical education, having spent twelve years in undergraduate medical education where I held various positions from academic skills specialist to Assistant and Associate Dean for Curriculum at the University of Illinois, Urbana and Geisinger Commonwealth School of Medicine in Pennsylvania. I am fascinated with the complexity of graduate medical education and am excited to see medical students transition to physicians.
