Evolutionary demography


My research focuses on the mechanisms driving population dynamics, with a specific interest in how evolutionary and ecological processes interact to shape life histories and population responses trajectories in free-living birds and mammals in interaction with human activities. Beyond theoretical interests, I am also motivated by using these results to predict species’ responses to environmental changes and inform conservation actions.

Current projects :

1) Population dynamics of the polar bear in Svalbard, in collaboration with the Norwegian Polar Institute, Jon Aars,Olivier Gimenez and Nigel Yoccoz.

We are currently trying to understand the ecological and evolutionary drivers of polar bears’ reproductive strategies. I am also using polar bears as a study case to understand the evolution of reproductive strategies in extreme environments and evaluate the impact of global warning on Arctic species.

2) Mathematics of kinship demography, in collaboration with Samuel Pavard, Christophe Coste and Victor Ronget.

This project aims at investigating the dynamic interplay between social behaviors, kinship structure, population dynamics and evolution of life history traits, using humans and social vertebrates as model species. This is important, for instance to better forecast viability of social species or investigate the coevolution of social and demographic traits. To do this we will provide new tools to investigate the mathematical relationships between the dynamics of structured populations and their kinship structure.

3) Understanding the determinants of ageing trajectories, in collaboration with JM Robine and the working group ‘The metrics of longevity’ composed of French demographers and evolutionary biologists.

We are interested in comparing the patterns of ageing trajectories across the tree of life, and contrast various longevity metrics.


I am teaching statistics and programming with R to master students at EPHE since 2016 (30h/year).

Other teaching include a class on life history evolution, one on matrix models, one on phylogeny with R to master students at EPHE and practicals on population dynamics using ULM for master students at the university of Montpellier.
