Researcher biography
Associate Professor Sjaan Gomersall is Associate Director and Principal Research Fellow at the Health and Wellbeing Centre for Research Innovation at School of Human Movement and Nutrition Sciences and a Teaching and Research academic in Physiotherapy at the School of Health and Rehabilitation Sciences at The University of Queensland. Established in 2022, the Health and Wellbeing Centre for Research Innovation (HWCRI) is a collaborative, co-funded research centre by The University of Queensland and Health and Wellbeing Queensland. The HWCRI combines world class research expertise in physical activity, nutrition and health at The University of Queensland, with the reach and capacity of Health and Wellbeing Queensland to integrate, deliver and evaluate evidence-based programs that provide scalable, equitable access to improve the health and wellbeing of all Queenslanders (and beyond).
Associate Professor Gomersall is an expert in physical activity, sedentary behaviour and health. Her research has focused on understanding, measuring and influencing physical activity and sedentary behaviour using a variety of methods and with a range of populations, with a focus on adults, the prevention and management of chronic disease and physical activity promotion in healthcare settings. Sjaan has a strong track record for multi-disciplinary collaborations and industry partnerships, with specific expertise in partnering with healthcare organisations to build capacity in research and physical activity behaviour change, to evaluate the impact of healthcare services and to co-design and test innovative solutions to gaps in service delivery. Dr Gomersall is a nationally and internally recognised leader in physical activity and health. She is the President-Elect of the International Society for Physical Activity and Health, Co-Lead for the Physical Activity in Healthcare Special Interest Group for the Asia-Pacific Society for Physical Activity, a Consultant for Physical Activity for the World Health Organisation and an Associate Editor for the Journal of Activity, Sedentary and Sleep Behaviours.
