Current Research Topics

I am interested in understanding how fish and lampreys respond to environmental stressors or anthropogenic disturbances. Combining experimental and field approaches, I investigate the plastic and adaptive component of this response to provide insights to predict the influences of environmental changes on populations.

My work at UMR ESE is developed around one central question: In the context of global warming, how do multiple stressors, including temperature, interact to alter fish life history traits (LHT), physiology, and reproductive success. I focus on both (pre-) spawning and early stages (i.e. embryos and larvae). My working hypothesis is that higher temperatures in rivers will increase metabolic rates and; therefore, will directly influence fish physiology, and possibly sensitivity to other stressors, such as hypoxia or the fragmentation of habitats.

I continue to be involved in projects initiated during my former position between 2012 and 2017 in UMR CARRTEL (Thonon-les-Bains, France, on the shores of Lake Geneva) on the evolutionary ecology of lake fish (namely Coregonus lavaretus and Salvelinus alpinus). These projects focus on the early stage response of these cold water stenothermic species to climate change, especially the increase in temperature.
