Dr. Pascal Crépey, Professor at the French School of Public Health, focuses his research on pivotal areas within epidemiology and biostatistics. With expertise spanning infectious disease modeling, epidemiological surveillance utilizing big data, and the economic aspects of preventive health strategies, Dr. Crépey is at the forefront of public health research.

He holds a PhD in biomathematics and biostatistics from Université Pierre et Marie Curie, Paris.

Tenured researcher and lecturer in the Health Services Research Team (RSMS – Inserm U 1309), within Unité Mixte de Recherche Arènes - UMR 6051 (EHESP, Université de Rennes, CNRS, IEP Rennes). 

Co-authors of more than fifty scientific articles published in peer-reviewed international journals.


For more than two decades, Dr. Crépey has studied the intricacies of influenza dynamics, making substantial contributions to our understanding of its epidemiological mechanisms. In response to the COVID-19 pandemic, it quickly redirected its efforts to analyze its dynamic nature and evaluate the effectiveness of various mitigation strategies. His recent research explores the complex interplay between COVID-19, RSV, and influenza, particularly focusing on the potential impact of non-pharmaceutical interventions on the trajectories of these epidemics.

At the same time, Dr. Crépey spent several years studying the dynamic structure of health networks and its influence on the spread of antibiotic-resistant bacteria at regional, national and transnational levels. Its objective is to propose effective strategies to control the spread of these bacteria, thus responding to a major public health concern.
