Sandrine Depeau is a CNRS research fellow in environmental psychology at UMR ESO, Université Rennes 2. Her work focuses on children's daily spatial mobility in urban environments, using an ecological and relational approach based on in situ methods. By specifically studying the process of children's spatial autonomy, she is interested in the environmental and psycho-social factors involved in the development of active mobility. She led the interdisciplinary MOBI'KIDS program (ANR 2017-2022) - a longitudinal investigation into the evolution of child and family mobility in Rennes.
