My research focusses on biopsychosocial determinants of couple functioning and violence. I am particularly interested in 1) the role of psychophysiological reactivity in violent couples' communication behaviors and 2) the impact of partners' personality on various aspects of couple functioning. 

I am also interested in the influence of social networking sites on adolescents and young adults' romantic relationships. My research focusses on the ways youth use social networking sites and how their online behaviors shape intimacy, conflicts and romantic relationship quality.

My research work addresses different themes linked to couple relationships, in the general population and in clinical populations. First of all, the adult attachment theory shapes much of my research. Drawing inspiration from this theoretical model, I examine the close bonds between attachment, conjugal support and sexuality, to better understand the dynamics of conjugal relations among different populations of couples. Second, I am especially interested in infertility. My work aims at 1) assessing the psychological, conjugal and sexual impacts of this problem, 2) assessing the specific needs of couples undergoing infertility treatment and 3) developing interventions for optimizing these couples' well-being. Lastly, conjugal abuse and dyadic coping are also among my fields of interest.
