Je suis écologue, spécialisé en écologie des populations et en statistiques appliquées à l’écologie (mark-recapture, occupancy, etc.). Mes travaux actuels se concentrent principalement sur l’étude des impacts de l’éolien sur les populations d’oiseaux.
I am a quantitative ecologist. I specialize in population ecology and ecological statistics (mark-recapture, occupancy, etc.). My current work mostly focusses on studying the impacts of wind energy development on bird populations.

About me
Français
Je travaille à l’interface entre recherche fondamentale et conservation de la biodiversité. Ma principale motivation est de comprendre et d’atténuer l’impact des activités humaines sur la biodiversité. Mon domaine de prédilection étant l’écologie des populations, je m’intéresse surtout aux impacts à l’échelle des populations animales, mais pas uniquement. Les méthodes que j’utilise s’appuient beaucoup sur la modélisation (projections démographiques, notamment) et sur l’analyse statistique de données de suvis de la faune (comptages, capture-recapture, occupancy). Je travaille de près avec de nombreux acteurs de la biodiversité, sur des projets touchant à de nombreux taxons de vertébrés : oiseaux marins, oiseaux terrestres, mammifères terrestres, phoques, amphibiens.
Actuellement, mes travaux de recherche se concentrent sur l’étude des impacts de la transition énergétique, notamment du développement de l’éolien, sur les oiseaux. Dans le cadre du projet MAPE, j’ai notamment développé une application Shiny (EolPop) qui permet de quantifier l’impact démographiques des collisions d’oiseaux avec les éoliennes. J’ai ensuite développé l’application EolPower, qui permet de dimensionner les suivis réalisés sur les parcs éoliens pour estimer la mortalité aviaire. Depuis 2022, je travaille sur le projet BIRD DYNAMIC qui a pour objectif d’estimer l’impact cumulé des parcs éoliens en mer sur les populations d’oiseaux marins de la façade Atlantique française.

My work is at the crossroad between fundamental research and conservation. My biggest motivation is to understand and mitigate the impact of human activities on biodiversity. My main area of interest is population ecology. Therefore, my research mostly focusses on impacts at the population scale, but not exclusively. The methods I use rely heavily on modeling (demographic projections, in particular) and statistical analysis of wildlife monitoring data (counts, capture-recapture, occupancy). I work closely with many biodiversity stakeholders, on projects involving a wide range of vertebrate taxa: seabirds, land birds, terrestrial mammals, seals and amphibians.
Currently, my research is focused on studying the impact of the energy transition, particularly the development of wind power, on birds. As part of the MAPE project, I developed a Shiny application (EolPop) to quantify the demographic impact of bird collisions with wind turbines. I then developed the EolPower application, which helps defining the study design of carcass search surveys that are carried out on wind farms to estimate avian mortality. Since 2022, I have been working on the BIRD DYNAMIC project, which aims to estimate the cumulative impact of offshore wind farms on seabird populations along the French Atlantic coast.
