Day 2

“Methods for collecting physical activity data and state of knowledge in the field of physical activity, sedentary behavior and health, including new tools/sensors and practical work with the use of an accelerometer”
Jérémy VANHELST

Day 3

“Building evidence in public health nutrition and the contribution of large French cohorts: from SU.Vi.MAX to NutriNet-Santé”
Mathilde TOUVIER

Day 4

“Nutritional profiles / Nutri-Score as examples of public health nutrition policy, from research to action, and practical workshop ‘calculating the Nutri-Score'”
Chantal JULIA, Cédric AGAËSSE

Day 5

“Evaluating nutrition among specific populations: contributions of participatory research”
Alice BELLICHA

“Nutrition, Physical Activity and Cancer Research Network (NACRe): role in multidisciplinary research and knowledge transfer to the public (patients, citizens, healthcare professionals)”
Bernard SROUR

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.

Mathilde Touvier is Director of Research at Inserm and principal investigator for the NutriNet–Santé cohort. She is a graduate of AgroParisTech and holds a PhD in epidemiology and public health. After six years at the French Agency for Food, Environmental and Occupational Health & Safety (Anses) and a year as a visiting researcher at Imperial College London, she joined the CRESS-EREN Nutritional Epidemiology Research Team (U1153 Inserm/Inrae/Cnam/ Sorbonne Paris Nord University / Paris Cité University), which she took over as director in 2019. She coordinates research on the links between nutrition and health (e.g. principal investigator of an ERC Consolidator Grant 2020-2025 project on industrial food, additives, food processing and health), with >370 publications in this field. She is an expert advisor to several institutions, including the French National Cancer Institute (INCa), the Ministry of Higher Education and Research (France 2030 ambassador) and the international Global Burden of Disease network. She is a member of the Scientific Council of the International Agency for Research on Cancer (WHO-IARC). She received the Inserm Research Prize in 2019 and a prize from the Bettencourt-Schueller Foundation in 2021. She has just been appointed Professor at the Collège de France in Public Health for an annual chair in 2022-2023.

Jérémy Vanhelst is a senior lecturer in exercise physiology at Sorbonne Paris Nord University (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).
