Welcome to the CEFE

The CEFE is currently the largest French research center in Ecology and Evolutionary Ecology. Our Mission: perform independent, fundamental scientific research on the dynamics of biodiversity, planetary environmental change, and sustainable development. The links between society and ecology is a theme of increasing importance in oour research.

If you are interested in who does what on a specific theme or topic at CEFE, please go to the WHO DOES WHAT tab and use the proposed tags. You will have direct access to the pages of the persons listed for a given tag.

If you are interested in what the different research Departments at cefe do and the focus of their respective teams, please go to the RESEARCH tab and navigate the Departments and their teams.

Postdoctoral Researcher

My research interests lie at the interface between population dynamics, quantitative ecology, conservation and life history evolution. I mostly focus on empirical work, on wild animal populations, but I also do some methodological development and a bit of theoretical work.

My research interests lie at the interface between population dynamics, quantitative ecology, conservation and life history evolution.
I mostly focus on empirical work, on wild animal populations, but I also do some methodological developments and a bit of theoretical work.

For my current postdoc (with Aurélien Besnard), I work on the population dynamics of Golden Eagles (Aquila chrysaetos) and we are developing an adaptive monitoring program for this species, in collaboration with French National Parks.

I have worked on several vertebrate taxa: birds, marine mammals and amphibians.
