Research Interests

 

I'm an evolutionary biologist using population modeling to study life history trait evolution, genetic diversity, demography and conservation biology. I worked on various topics (human evolution, evolution of migration, evolution of altruism, footprint of selective sweeps, etc. see papers below).

 

Actually, I am especially working on modelling the mating system evolution and their demographic consequences, especially in plants but also in fungi, and in general...
