I am a conservation biologist interested in the human pressures on biodiversity (i.e. communities, functional traits, behaviour). I try as much as possible to make my work applied in order to propose solutions to limit human's footprint on ecosystems and understand what are the most effective possibilities for change in our society today.

My work focuses around several major themes:

  • the biodiversity-agriculture relationship, mainly focused on agricultural practices linked to inputs and tillage. In particular, I work on small changes realist for farmers in conventional farming which generate strong ecological gains for biodiversity, by studying farming systems that do not result in yield losses.

  • the impact of wind energy on biodiversity: in particular, I am studying a type of impact that has so far been ignored by assessment impact studies and the environmental authority, habitat loss by revulsion. I also work on metadata needed in French environmental assessment/monitoring studies to answer a wide range of questions, and how standardize the data transmitted by the consulting offices at national scale.

  • the ecological offsetting and ecological equivalence in farming contexts, which is a particularly applied subject that aims to (i) quantify the habitat losses generated by any development project to make them compensable and (ii) find equivalent alternatives in terms of biodiversity to a given offsetting measure, in order to facilitate the implementation and to contextualize offsetting to avoid blocking situations.

  • the artificial light at night (ALAN), for which my work focuses mainly on the spatial variation of effects on biodiversity as a function of the landscape context, as well as on changes in bat behaviour in relation with light parameters, and in particular changes in the use of ecological corridors for moving and foraging.

Such societal issues often involve to work directly with stakeholders and to understand the social levers to transfer my research into the real life, seeking the best trade-offs to prevent this new knowledge from ever being useful in halting the decline of biodiversity.
