My research focuses on adaptive evolution. I aim to understand how the underlying mechanisms of adaptation affect genetic and phenotypic diversity in natural populations, as well as population growth and persistence in changing environments. In recent years I have been particularly interested in adaptation to randomly fluctuating environments. I combine theoretical modeling, experiments in the laboratory (including experimental evolution) with microalga Dunaliella salina, and analyses of natural populations. 

Check my personal website for more details. 

Keywords: Genetics of adaptation, Phenotypic plasticity, Eco-evolutionary dynamics, Evolutionary rescue, Pleiotropy, Parallel evolution,Selective Sweeps.

Thèmes de recherches 

Ma recherche a pour objet l'évolution adaptative. Je cherche à comprendre commebt les mécanismes sous-jacents à l'adaptation influencent la diversité génétique et phénotypique dans les populations naturalles, ainsi que la croissance et la persistance des populations en environement changeant. Ces dernières années, je me suis particulièrement intéressé à l'adaptation aux environnement qui fluctuent aléatoirement. Je combine modélisation théorique, expériences au laboratoire (dont l'évolution expérimentale) avec la microalgue Dunaliella salina, et analyse de populations naturelles.
