Ollie is an Associate Professor in Thermoregulatory Physiology, and Director of the Thermal Ergonomics Laboratory, in the Faculty of Health Sciences at the University of Sydney, and Lead Researcher of the Charles Perkins Centre (CPC) Research Node on Climate Adaptation and Health. Prior to moving to Australia in January 2014, he was a tenured Associate Professor at the University of Ottawa in Canada (2008-2013). Originally from the UK, he obtained his PhD in Thermal Physiology from Loughborough University in 2002, which was then followed 4½ years of international postdoctoral research experience at Simon Fraser University (2003-05) and the University of Ottawa (2005-08). His research activities primarily focus on developing a better understanding of the physiological and physical factors that determine human heat strain and the associated risk of heat-related health problems during work and/or sport, as well as among the general population during heat waves.
To date, he has a total of 100+ peer-reviewed research publications in international journals (70+ as senior author), and has received funding from organisations such as the National Health and Medical Research Council (NHMRC), MS Research Australia, NSW Office of Environment and Heritage, US Department of Defense, National Rugby League (NRL), Cricket Australia and General Electric (GE). He is also an Associate Editor for Journal of Science and Medicine in Sport (JSAMS), and Temperature, as well as an Editorial Board member for Journal of Applied Physiology, and Medicine and Science in Sports and Exercise (MSSE).
Ollie is a Fellow of the American College of Sports Medicine (ACSM), has been regularly invited to speak at international conferences, and was the recipient of a 2017 University of Sydney Vice-Chancellor's Award for Outstanding Research and Teaching. He has active research collaborations within Australia, Canada, USA, and UK, and his research has featured in articles/interviews for the New York Times, BBC, ABC, CBC, NPR, Sydney Morning Herald, The Globe & Mail, The Weather Channel and Scientific American.
