Ph.D.
Associate Dean
Biography
Dr. Bell is a Professor of Physiology and serves as the Assistant Dean of Foundational Sciences Education for the CMU College of Medicine. In this role, he provides leadership and oversight for the first two years our undergraduate medical education program. Dr. Bell joined the College of Medicine as one of our inaugural faculty in 2012 and was appointed Assistant Dean in 2018. A physiologist by training, he received his bachelor’s, master’s and doctorate degrees at the University of Toronto, Canada. He went on to complete postdoctoral training at the University of Calgary and Penn State University (Hershey) before being appointed Assistant Professor of Medicine and Cellular and Molecular Physiology at Penn State in 2010. Dr. Bell has played an instrumental role in development and accreditation of the pre-clerkship education program, and has served as Course Director for the Cardio Pulmonary Wellness and Disease course block since the first iteration of the course in 2013. A successful educator, he is an advocate for student-centered and active learning approaches, and works to promote a safe and open environment for students to begin to develop their sense of professional identity. Dr. Bell remains actively engaged in the research community and enjoys providing students with valuable research experiences by engaging them in his ongoing research program, focused on disorders of respiratory control.
