Research interests

My current work focuses on the relationship between sleep, public health and human performance. My research program focuses on two complementary research axes: 1) Characterizing the environmental, social and behavioral determinants of sleep health; 2) Characterizing cognitive, physical and mental sleep health outcomes.

Methodological approaches

Actigraphie, polysomnographie, questionnaires, Tâches mesurant des performances cognitives et physiques.

Chronobiology of Antarctic Isolation: the use of Belgrano II Antarctic Station as a Space Analogue

This study is a one-year longitudinal study evaluating the chronobiological impact of a wintering mission in Antarctica. We are studying a total of 20 healthy crew members (including scientists and military personnel) who will spend a year at the Belgrano II research station in Antarctica. Belgrano II comprises a series of scientific research facilities on the continent more specifically at Nunatak Bertrab, facing the Weddell Sea (77 ° 51S and 34 ° 33W). The primary objective of this study is to assess changes in sleep, circadian patterns, social interactions, mood, alertness, and decision-making among crew members during this mission to a year in Antarctica.

COHESION Study: COvid-19, HEalth and Social InteractiOn in Neighborhoods

COHESION is a longitudinal study aimed at capturing perceptions and attitudes towards COVID-19 and related societal containment measures, spaces for daily activities, sleep, social interactions as well as the mental health of individuals and households across Canada throughout the COVID-19 pandemic.
