Thèmes de recherche

I work in social psychophysiology within a behavioural biology perspective. I am interested in understanding the effect of stress on cooperation and conversely. I am looking for common mechanisms across different species. I also have projects dealing with methodology, epistemology, and data analysis. My current research works follow open, slow and sustainable science practices as much as possible.
