My interests lie in experimentally understanding the traits linked to organisms' success in a warming climate at various levels of biological organization. One of my study interests deals with the impacts of climate change on common lizards from the individual level – which phenotypic traits are linked to individual success – to the population and community level. I also work on smaller species, with a more community-based framework, as I am investigating experimentally the traits linked to competition between species in different climatic conditions in phytoplankton communities, and to how climate and habitat fragmentation shape phytoplankton and zooplankton communities.
