In April 2022, CY Initiative, with funding from the Ile-de-France Region, launched the Human and Social Sciences Chair headed by Marie Kerveillant, a research engineer at ESSEC.In the midst of the Covid 19 health emergency, hospital structures were put to the test over a long period of time. Before that, some hospitals had experienced other major crises, such as the massive influx of injured people during the terrorist attacks in Paris and Nice. It seems essential for these hospital structures, and in particular for the crisis medical departments, to develop their resilience in the face of the various crises they may be confronted with in in the future. This chair aims to work on the role of crisis medical departments within hospital structures, to see how they have evolved since the Covid 19 health crisis, and how they could improve their resilience.Interview with Marie Kerveillant, holder of the Human and Social Sciences Chair.
