After working on fundamental research during her thesis (Laboratoire de Régulation des Gènes et Signalisation Cellulaire, INSERM) and her postdoctoral training (Laboratoire de Biologie Intégrée des Cellules Rénales, CNRS/CEA), Cécile turned to more applied research and joined INRA as a research fellow in 1998. She was recruited to the NASA (Nutrition, Food and Food Safety) department in the team headed by A. Grynberg (Membrane lipids and cardiovascular functions). In 2004, she took part in the formation of UMR 1154 (Lipid Nutrition and Functional Regulation of the Heart and Vessels). For 9 years she worked closely with A. Grynberg on the prevention of cardiovascular disease through diet.
In September 2007 she joined the Unit 1089 Xenobiotics at Tolouse in the Biottox team. To stay within the field of diet-induced metabolic diseases and energy metabolism studies, while integrating the effects of xenobiotics, her research projects focused on the obesogenic effects of Bisphenol A and then its substitute Bisphenol S.
In 2012, she joined the PPCF team. For the past 12 years, she has worked mainly on changes in energy metabolism during carcinogenesis. She is developing projects focusing on the prevention of human diseases through diet, using a dual approach: animal models and cellular models.
