Marion Lecorguillé

Post-doctoral researcher

After graduating as a midwife, I continued my studies in the field of public health research and I obtained my PhD in epidemiology in 2020, which focused on the associations between maternal nutrition in preconception, fetal development and placental epigenetics. My first postdoctoral experience at University College Dublin investigated the role of parental diet in the prenatal period with offspring epigenetic associations within the European ALPHABET consortium. I am currently working as a postdoctoral researcher at the National Institute of Health and Medical Research in Paris (INSERM) within the EAROH team, dedicated to the study of the early determinants of child development. I carry out my research work as part of the European EndObesity consortium(https://www.healthydietforhealthylife.eu/index.php/projects/research-area-supported-project/report/465), which includes important research questions on prevention strategies for childhood obesity, targeting family lifestyle factors in the first 1000 days of life. I am also involved in other research projects on the social inequalities in child nutrition in the first years of life.
