INRAE, UMR MoISA, France
- Marlène PERIGNON is a research engineer in nutrition and public health at INRAE, within the MoISA Joint Research Unit in Montpellier (https://umr-moisa.cirad.fr/)
- Her research focuses on social inequalities in access to sustainable diets. She investigates strategies to reduce these inequalities through two complementary research approaches: (i) Population Health Intervention Research (PHIR), to evaluate programmes designed to improve access to sustainable diets among vulnerable populations by examining their effectiveness, implementation, mechanisms of impact, and transferability; and (ii) observational and modelling approaches, including constrained optimization, to characterize population diets in terms of nutritional quality, environmental impact, and cost, and to identify food choices and food provision strategies (e.g. in school meal programmes and food aid) that reconcile the multiple dimensions of sustainable diets.
- She conducts her research primarily in mainland France and the French overseas territories, particularly Guadeloupe.
- She is the scientific leader of the PASSERELLE PLUS project in France (https://passerelle-plus.hub.inrae.fr/)
