Projects

My research aims to better understand how social life has evolved. To this end, I study the relationship between the social context and individual performances, especilly in terms of survival and reproduction. During my PhD, I focused on the process of competition between individuals of the same sex in family groups.

I’m currently working as postdoctoral researcher at the CEFE in Montpellier.
