Overview
Background
Gregore is a behavioural epidemiologist and Principal Investigator of the HABITAT Study, an ongoing cohort focused on urban environments, physical activity, inequalities, and healthy ageing. His research explores how physical activity and sedentary behaviour change over time, from early childhood to older age, particularly during major life transitions, and how these patterns relate to health outcomes and inequalities.
He has a strong interest in improving the measurement of physical activity in population surveys and in applying life-course perspectives to better understand behavioural trajectories and inform strategies to reduce health disparities. Gregore has published more than 160 peer-reviewed papers, secured $4 million in competitive research funding (including>$1 million as Chief Investigator), and actively contributes to national and international initiatives to strengthen physical activity surveillance and public health policy.
Gregore is a Teaching and Research academic at the School of Public Health, where he leads a multidisciplinary research group with PhD and Master’s students working on physical activity epidemiology and life course research projects. He is also an NHMRC Emerging Leadership Fellow (EL1; 2022–2026) and serves as Deputy Editor for the Journal of Physical Activity and Health.
