Main research topics

My research lies at the interface between evolutionary ecology, behavioural ecology and eco-physiology. I am interested in the effects of the biotic and abiotic environment on the life-history traits, the physiology and phenotype of the organisms.
In particular, I study the effects of the parental environment on their young (maternal effects or transgenerational effects) and the effects of the early life conditions on the developing young. I focus on the effects of abiotic conditions changing rapidly these past decades: the effects of climate change and, more recently, the effects of urbanisation (collaboration with Sylvie Massemin-Challet). Concerning the biotic environment, I am starting a project on the effects of the social environment (collaboration with Vincent Viblanc).
I also investigate evolutionary trade-offs between different life history traits thanks to individual-based long-term monitoring of wild populations.

Keywords: Antioxidants, Climate change, Global changes, Life history traits evolution, Maternal effects, Oxidative stress, Phenotypic plasticity, Population ecology, Reproductive costs, Senescence, Trade-offs, Urbanisation.
