le groupe

We are always, as a group, very enthusiastic about welcoming new group members. If you are applying to work with us, as a master or PhD student, or as a postdoc, this page is made to help you discover before hand who we are and how we work. Then perhaps you will think better (yes, pun intended, get used to it).Mostly, this page is intended to present the group, but also to give you an idea of what to expect from me and from yourself. I hope your time here will be rewarding and fun.

I work on population dynamics for conservation biology and run the lab « Biodiversity Dynamics » with all the great people below.
