My research topics relate mainly to the analysis of the psychological adaptation processes in the field of extreme or constraining situations (high-level sport; high terrestrial altitude; polar stations and expeditions; space situations) with for example the European and French Space Agencies (ESA and CNES) and the French Polar Institute (L'Institut Paul Emile Victor (IPEV). As a practicing psychologist, I intervene in the psychological preparation of the participants subjected to these extreme situations.
