Bronwyn Clark

Dr Bronwyn Clark is a lecturer and researcher in the School of Human Movement and Nutrition Sciences, Faculty of Health and Behavioural Sciences, at the University of Queensland. She obtained her PhD in 2011 from the School of Population Health at the University of Queensland, where her thesis was titled 'Measurement of Adults' Sedentary Behaviour by Questionnaire'. Clark's academic interests lie in the epidemiology of physical activity and sedentary behaviour, with a focus on developing and validating measurement tools such as questionnaires and device-based methods for assessing sitting, standing, and stepping patterns in occupational and free-living contexts. Her work explores prevalence, trends, correlates, and health impacts of sedentary time, including associations with cardiometabolic risk factors.

Clark has held an NHMRC Early Career Fellowship for the project 'Sitting, Standing and Moving: Evaluating the impact of health enhancing initiatives' spanning 2016 to 2022. She contributes to the Physical Activity and Health research group, investigating psychosocial factors, interventions, and technologies like Bluetooth sensing and mmWave radar for behaviour measurement. Key publications include 'Measurement of adults' sedentary time in population-based studies' (Healy et al., 2011, American Journal of Preventive Medicine), 'Occupational sitting and health risks: a systematic review' (van Uffelen et al., 2010, American Journal of Preventive Medicine), 'Validity and reliability of measures of television viewing time and other non-occupational sedentary behaviour of adults: a review' (Clark et al., 2009, Obesity Reviews), 'Field evaluation of a random forest activity classifier for wrist-worn accelerometer data' (Pavey et al., 2017, Journal of Science and Medicine in Sport), and recent articles such as 'Device-based measurement of office-based physical activity and sedentary time: a systematic review' (Bongers et al., 2024, Journal for the Measurement of Physical Behaviour) and 'Barriers and facilitators to increase physical activity and reduce sedentary behavior in Ethiopian office-based employees: a qualitative formative research using the social-ecological model' (Negussie et al., 2025, Journal of Activity, Sedentary and Sleep Behaviors). She coordinates courses including HMST4925, supervises higher degree research students, and has produced datasets like 'Where and When at Work - validation of Bluetooth identified locations in work environment' (2018). Her research informs strategies to reduce prolonged sitting and promote healthier work practices.
