Postdoctoral Fellow

My work focuses on the prediction of mental health problems (suicide, depression, anxiety…) among adolescents and young adults. My research utilizes machine learning approaches and national and international population-based cohorts (QLSCD, QLSKC, i-Share) to predict mental health problem.

I have a bachelor degree in biology from the University of Pau and Pays de l’Adour (UPPA) and a master in biostatistics from the Bordeaux School of Public Health (ISPED), in France. I completed a PhD, in Public Health, Biostatistics in the Healthy Team of the Bordeaux Population Health research center, in France. I am currently a post-doctoral fellow and I work on the EpiCov project, which studied the impact of Covid-19 health crisis on adolescents’ mental health.
