Head of the EREN’s dietetics division, Cédric Agaësse works mainly on projects related to the Nutrinet-Santé study, such as the ADDITIVES and Nutri-Score projects, as well as on validating and improving the data in the nutritional composition tables used by researchers and other colleagues at the EREN.

With a degree in engineering from AgroParisTech specialising in human nutrition, Mélanie Deschasaux-Tanguy chose to pursue a PhD in nutritional epidemiology to understand the links between nutrition and health and thus contribute to improving the health of the population. She initially focused her work on the links between nutrition and cancer risk, and is now more broadly interested in the links between nutrition and chronic diseases and the mechanisms underlying these relationships. She is currently developing research on the links between nutrition, gut microbiota and health and coordinates the ‘microbiota’ section of the NutriNet-Santé cohort. She also contributes to other research conducted within EREN, notably on Nutri-Score, food processing and additives, and COVID-19.

Dr Mathilde Touvier is a Research Professor (DR1) at the French National Institute for Health and Medical Research (Inserm), principal investigator of the NutriNet-Santé cohort (n=182 000, 2009-ongoing, https://etude-nutrinet-sante.fr/). She graduated from AgroParisTech in Human Nutrition in 2002 and obtained a PhD in Epidemiology and Public Health in 2006. After six years at the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) and one year as a visiting researcher at Imperial College London, she joined the Nutritional Epidemiology Research Team CRESS-EREN (Inserm / Inrae / Cnam / Université Sorbonne Paris Nord / Université Paris Cité), of which she became Director in 2019. She coordinates researches on the links between nutrition and health (e.g. PI of a European Research Council ERC Consolidator Grant 2020-2025 on the impact of industrial food, food additives and food processing on health; PI of the Impact Santé Foodcontact projet 2024-2028), with >500 publications in this field. She co-developed the front-of-pack logo Nutri-Score (L’Express Prevention Award 2025). She is expert in several workshops, e.g. at the French National Cancer Institute (INCa), the Ministry of Higher Education and Research (France 2030 ambassador), the international network Global Burden of Disease. She received the Inserm Research Prize in 2019 and a prize from the Bettencourt-Schueller Foundation in 2021. She has been appointed Professor at the College de France in Public Health for 2023. She received the ERC Public Engagement with Research Award 2024.

Jérémy Vanhelst is a senior lecturer in exercise physiology at Université Sorbonne Paris Nord (USPN), in the Department of Sports Science (STAPS). After 12 years at Lille University Hospital (paediatric research department) as a researcher, he joined the Nutritional Epidemiology Research Team (EREN-CRESS) in September 2022. His research focuses on the relationships between physical activity, sedentary lifestyles, physical fitness and health. He also works on surveys monitoring physical activity and physical fitness in France. Finally, he is also studying the development of tools for measuring physical activity in normal living conditions. He is a member of the scientific committee of ONAPS (National Observatory of Physical Activity and Sedentary Lifestyles).

Alice Bellicha is an Assistant Professor at University Sorbonne Paris Nord and at the CRESS-Nutritional Epidemiology Research Team. Her research projects aim at supporting changes in nutritional behaviors (diet, physical activity) in a perspective of prevention and management of chronic diseases. She’s currently developing a participatory research project involving the student population of the University Sorbonne Paris Nord, with the aim of better describing the nutritional behaviors of students and proposing interventions likely to promote their access to a sufficient, healthy and sustainable diet. She’s also co-director of the master 1 and 2 Human Nutrition and Public Health (Bobigny campus).

Bernard Srour is a pharmacist and epidemiologist by training. He’s enjoy investigating the links between “nutrient-unrelated” aspects of the diet (meal timing and circadian rhythms, food processing, additives…) and chronic diseases, in particular some cancers and metabolic health. He also leads the NACRe network, a French (very soon becoming European) network on nutrition and cancer research (my favourite topic), and coordinate actions on research networking, healthcare professionals training, and scientific communication. When he’s not working, you will definitely find his cooking, playing in amateur/semi-professional theatre plays, watching series, or jogging (since very recently).

Professor Chantal Julia is a public health nutritionist, Head of the Department of Public Health at the Paris–Seine–Saint-Denis hospitals (France), and a senior researcher in the Nutritional Epidemiology Research Team (EREN) at Sorbonne Paris Nord University. As a nutritional epidemiologist, she conducts population-based research—including observational studies in the general population and specific groups, as well as intervention studies—to assess the relationship between dietary behaviours and health, with a particular focus on the evaluation of public nutrition policies. She contributed to the development and validation of the Nutri-Score in France and is internationally recognised as an expert in front-of-pack nutrition labelling and nutrient profiling.
