Pauline Hosotte is a doctoral student at the Urban Sociology Laboratory of the EPFL and a project engineer at Transitec Ingénieurs-Conseils. As a civil engineer with a degree from the same university, she combines the fields of transport engineering, spatial planning and social sciences to advance the understanding of changes in mobility behaviour and the parameters underlying their observable form. After working on high mobility practices in Europe and Chile, it is also with an international flavour that she is working on the controversial phenomenon of traffic evaporation. Through a close link with practice, it aims to clarify the diversity of social demands, so that urban public intervention can be calibrated to meet them.
