I am a research scientist at Inserm, in the EAROH team of the CRESS. I lead research in perinatal and pediatric epidemiology, on the factors influencing child and health development. Among these factors, I focus on the role of the lipids and fatty acids (pregnancy diet, breastfeeding), physical activity of pregnant women and children, and screen use of children. I work on large cohort studies of children, including EDEN (https://eden.vjf.inserm.fr/), Elfe (https://www.elfe-france.fr/), GUSTO (https://www.gusto.sg/about/) and S-PRESTO (https://www.s-presto.sg/). I am also the scientific lead for the iEDEN (follow up at 17-20 ans of EDEN children) and involved in several thematic working groups of the Elfe and Marianne (https://cohorte-marianne.org/) studies.
