Location: WCM Qatar


Research Areas

Research Summary:

Dr. Sean Holroyd joined Weill Cornell Medicine – Qatar (WCM-Q) in January of 2017.  Prior to coming to WCM-Q he served as a Lecturer of Physiology at James Cook University, where he was course director for physiology for 2nd Year biomedical science students and Year 2 coordinator for Veterinary Science. Dr. Holroyd has extensive teaching experience having taught organ systems physiology to medical, veterinary, pharmacy, nursing and biomedical science students at a number of institutions.  Throughout his career he has received multiple teaching awards from James Cook University, St George’s University and the Australian College of Educators. Dr. Holroyd has held administrative leadership positions including Deputy Head of the Department of Physiology and Neuroscience, Associate Dean of Students at St George’s University, and course director of a wide span of courses both undergraduate and postgraduate. He has been actively involved in leading curriculum development at a number of institutions where he has developed course, degree and integrated curricula. Dr. Holroyd received his Ph.D. in Physiology from Monash University in the field of muscle energetics.  His research interests remain in this area with the emphasis on the mechanisms of airway smooth muscle response during exercise-induced asthma.
