Our teams: EREN

Nutritional Epidemiology Research Team (EREN) – CRESS, INRAE, Sorbonne Paris Nord University, France

I am an epidemiologist at the National Research Institute for Agriculture, Food and Environment (INRAE) and I have been working within the Nutritional Epidemiology Research Team (EREN) of the French epidemiology and statistics research center (CRESS) at the University of Paris and University Sorbonne Paris Nord since 2014.

I have always been curious about food cultures throughout the World, and how diet can be a strong factor influencing human Health in many aspects. This is why I love travelling including in my native country: France. I enjoyed a lot studied abroad, in a country now close to my heart: Quebec, Canada, with a first trip during an exchange program at the faculty of Nutrition at Université de Montréal. I had another experience in Quebec, Canada later: from 2010 to 2013, I studied and worked at Laval University in Canada as a PhD Student and post-doctoral fellow respectively, conducting studies about dietary patterns, circulating lipids, and cognitive decline in older people from France and Quebec.

My main research projects are now about the exploration of determinants of food behaviors or dietary patterns, focusing on plant-based diets and especially vegetarianisms, in relationship with Health, in the context of improving food sustainability.

I am also a lecturer in Nutritional Epidemiology at Sorbonne Paris Nord University, and teach at other Universities and engineering schools in France.

Besides my research activities, I have been involved in national expertise task forces with public authorities such as French ANSES, or international such as the evaluation of a public health nutrition policy for the European commission, or during workshop on food sustainability from WHO European NCDs office.
