Olivier Galy is Associate Professor, Director of the Interdisciplinary Laboratory for Research in Education at the University of New Caledonia, and scientific co-coordinator of the European Union project “Family farming, Lifestyle and Health in the Pacific” (H2020, MSCA-RISE 2020-2024). His expertise is in the area of exercise physiology, with a focus on understanding the impact on health outcomes of human activity (exercise, physical activity, inactivity, sleep) associated with individual and socio-environmental lifestyle factors. His original approach combines exercise physiology methods and knowledge with digital technologies to study lifestyle in free-living populations such as athletes, schools, families, communities.
