She is currently serving as a Senior Research Fellow in the Yong Loo Lin School of Medicine, National University of Singapore as technical lead of a project called “Cooling Singapore 2.0”, an interdisciplinary initiative aimed at determining how physical activity in the heat impacts vulnerable populations like children, heat-unacclimatised adults, and the elderly. This work is being conducted to better individualise global heat-health warning systems. Dr. Morrison is a Certified Clinical Exercise Physiologist from the Canadian Society of Exercise Physiology and Principal Investigator or member representative for the Republic of Slovenia on several international initiatives aimed to get kids moving, including: Active Healthy Kids Global Alliance, Outdoor Play Canada, the FitBack Network, and the Global Heat Health Information Network. Her studies on the neuromuscular demands of passive heat stress and cardiovascular strain in the heat have led her to advocate for greater public health engagement on harnessing physical activity as a climate change countermeasure, especially in the paediatric population.
