Mes recherches portent principalement sur les conditions de début de vie (nutrition, infections, statut socioéconomique) et leurs conséquences à long terme pour la santé et la longévité. Je complète ces recherches par une analyse des facteurs intermédiaires qui peuvent modifier ou même atténuer l’effet des conditions de début de vie, comme le niveau socioéconomique atteint à l’âge adulte, la mobilité sociale, la fécondité et la migration. Mes recherches portent également sur les épidémies et les pandémies, en particulier celles causées par la grippe et, plus récemment, la COVID-19. Elles accordent en outre une attention particulière aux implications évolutives et génétiques des comportements démographiques en général. Enfin, je développe actuellement de nouveaux projets portant sur l'insertion socioéconomique des immigrants et sur l’effet de sélection des immigrants en bonne santé dans un projet comparant la mortalité des immigrants et des natifs au Canada et en France.
