After obtaining my state midwifery diploma, I became involved in public health research and in 2020 I obtained a PhD in epidemiology on the links between preconception maternal nutrition, foetal development and placental epigenetics. My work has identified key associations between pre-conception weight variations, dietary intake, foetal growth and placental epigenetic mechanisms. As a postdoctoral researcher at University College Dublin, I broadened my research to examine the links between the diet and lifestyle of mothers and fathers and the epigenetics of their children.
I then joined the European EndObesity consortium and coordinated a work programme focusing on family health behaviours during the first 1,000 days of life and their influence on childhood obesity. I defined the research objectives and managed collaborations between several European institutions. At McGill University in Canada, I broadened my expertise in perinatal mental health and children's socio-emotional development. I developed strong skills in mixed methods and qualitative research. Finally, in September 2025, I rejoined the OPPaLE team to work on bariatric surgery and child development. |
