Scientific summary

Past Doctoral and Postdoctoral Research

My research focuses on early-life determinants of child development, with particular attention to the influence of parental nutrition and lifestyle during the first 1,000 days on child health, as well as the roles of migration and social inequalities. Following initial training in midwifery at the Faculty of Medicine in France, I obtained a Master’s degree in Public Health and Epidemiology in Paris, and subsequently completed a PhD on maternal nutrition before pregnancy, fetal growth, and placental epigenetics.Using the EDEN and Elfe French birth cohorts, my doctoral research examined how maternal dietary intake and weight changes during the preconception period may influence fetal development. During this period, I collaborated with the Epigenetics Epidemiology Team at the University of Bristol to investigate associations between maternal preconception dietary methyl-donor intake and placental epigenetic markers.During my first postdoctoral position at University College Dublin, I further explored the role of parental diet in the prenatal period with offspring epigenetic associations in the Lifeways Cross-generation cohort. I then joined a project conducted at Inserm in France as part of a European EndObesity consortium, where I coordinated a work package aimed at identifying the impact of family-based health behaviors during the first 1,000 days on childhood obesity risk. Seeking to broaden my methodological expertise, I undertook a third postdoctoral position at McGill University in 2024. My research focused on how pharmacological treatment of perinatal mental health disorders may influence subsequent child development. In parallel, I contributed to the development of a study protocol aimed at improving screening and referral pathways for perinatal depression.

Recent Research

More recently, I have joined the NUMASURG program “Maternal nutritional markers during pregnancy and health outcomes of the child: study in the general population and after bariatric surgery (BS)”, which aims to study the relationships between the nutritional status of pregnant women after BS and the outcomes of their pregnancies as well as the health of their children up to 4 years of age, with the aim of optimizing the quality of nutritional monitoring of pregnant women with a history of BS. This multidisciplinary program brings together clinical teams specializing in pregnancies after BS, biologists, members of the French Obesity Research Center of Excellence (FORCE), Inserm epidemiologists, and clinical research teams.
