Research expertise

My research interests focus on sexual assault of children and adolescents and I am a member of the Research Center of Interdisciplinary Research on Marital Problems and Sexual Assault (CRIPCAS). Two lines of research emerge from my work. The first aims to understand the variability of life trajectories after sexual assault during childhood or adolescence, including the involvement of processes such as resilience or psychotherapy in subsequent psychological functioning. The second focuses on primary, secondary and tertiary prevention of sexual assault of children and adolescents, including the effectiveness of interventions to reduce the incidence of sexual assault among youth. 

I lead the Research Laboratory on the trajectories of health and resilience of sexually abused young people: TRAJETS. TRAJETS focuses on all the life trajectories of young people who have been exposed to sexual violence during childhood or adolescence. First, we want to document the consequences of sexual assault on the physical and mental health of young people. In doing so, we examine how sexual assault interacts with different life contexts to produce more or less harmful consequences for young people and how these consequences evolve in the short, medium and long term. 

Risk factors that overlap sexual abuse, such as abuse or neglect, and protective factors that may coexist with sexual abuse or assault, such as social support, are central to our studies. These risk and protective factors allow us to better understand what facilitates or hinders the development of young people when they have been sexually assaulted. 

Through our studies, we want to help build the resilience of young people, their families and their environments.
