Emmanuelle LERAY is a Professor at EHESP (Ecole des Hautes Etudes en Santé Publique) specializing in epidemiology and public health. She serves as Director of U1309 Research on Health Services and Management (RSMS), an Inserm-certified team within the UMR Arènes. Her institutional affiliations include the Research Collective on Disability, Autonomy, Inclusive Society (CoRHASI), the Department of Quantitative Methods in Public Health (METIS), and UMR 6051 ARENES Course.

Dr. LERAY completed her thesis in epidemiology at the University of Rennes 1 in 2005 and obtained her HDR in 2017. After training at ISPED in Bordeaux, she worked in Burma as an epidemiologist for Aide Médicale Internationale before serving as University Hospital Assistant in the Epidemiology and Public Health Department of the Rennes University Hospital. She joined EHESP at the end of 2010 where she has established herself as a leading researcher in multiple sclerosis epidemiology.

Her research focuses on epidemiology of chronic diseases, particularly multiple sclerosis, examining care pathways, health services, and the impact of social determinants on health outcomes. She investigates developments in the health system, fights against social and territorial inequalities in health, and studies the organization, management, regulation and control of health services. Her work spans social and health policies with particular attention to disability, chronic illness, and health determinants.

Dr. LERAY coordinates the EU "Introduction to the methodology of epidemiological studies - part 1" for Master 1 public health at Rennes 1-EHESP and the Joint Public Health Seminar. She teaches epidemiology, biostatistics, and health observation, contributing significantly to public health education through her methodological expertise.

Her extensive publication record shows consistent focus on multiple sclerosis epidemiology, with particular attention to socioeconomic determinants of health, treatment access, disability progression, pregnancy outcomes, and healthcare utilization in MS patients. Her research connects clinical aspects of multiple sclerosis with broader health system organization and social determinants, often using large-scale data linkage approaches including the French multiple sclerosis cohort (OFSEP) and national health insurance database.

Dr. LERAY is actively involved in developing clinical guidelines, particularly regarding vaccinations and cancer management in multiple sclerosis patients. Her work bridges clinical practice and health services research, aiming to improve care pathways and reduce health inequalities for patients with chronic neurological conditions.
