RESEARCH

My research is focused on a comparative exploration of the role of multiple environmental drivers in shaping species distributions and diversity at multiple spatial and temporal scales. Most of my research is structured on the combined use of ecoinformatics methods (statistical analysis of large data sets) and naturalist expertise to understand empirical patterns of community composition in space and time. My main active axes of research include :  

- the influence of landscape and habitat on the distributions of birds and reptiles. Relying on opportunistic data from the regional participative database Malpolon, maintained  by the Ecole Pratique des Hautes Etudes since the 1980's, I investigate the determinants of spatial patterns in reptile distributions and diversity along regional gradients of climate, land use and land abandonment. See the MALPOLON database.

- Interacting imprints of climate change and land use on biodiversity. Using multiple taxa and scales, I investigate how species' responses to historical and present land use change interact with their responses to climate change. See the LANDBIO project (2022 - 2023, OFB - french ministry of ecology)

- Ecoacoustics and community ecology. I am currently starting projects on the relationship between bird community composition and the characteristics of acoustic landscapes at multiple spatial and temporal scales, in order to explore the acoustic environment in which species interact and its changes with current land-use and climatic dynamics. See the ACOUCENE project (2022 - 2025, FRB/CESAB)

COLLABORATIVE WORK WITH STAKEHOLDERS

Most of my interactions with biodiversity stakeholders are focused on data analysis to answer questions relative to the monitoring of human impacts on biodiversity at a regional or landscape scale.

- Influence of management practices on waterbirds. I investigate the impact of water management practices on the temporal dynamics of waterbird species (collaborations with the Ligue pour la Protection des Oiseaux). 

- Faunistic road casualties. I work with the Ligue pour la Protection des Oiseaux and the CEREMA to explain and predict spatial patterns in road casualites. We exploit jointly multiple sources of protocoled, non-protocoled and citizen science data to identify mortality hotspots and explanatory factors, with the final aim to inform public policies on the mitigation of traffic impact on vertebrates. 

TEACHING

Most of my teaching activity is embedded within the program of the Ecole Pratique des Hautes Etudes.

- Data analysis for ecologist : a three-weeks course dedicated to biodiversity stakeholders, framed on the practical use of statistical methods and the R software in ecological monitoring. 

- Methods for ecological monitoring : a two-weeks course with Aurélien Besnard, mainly dedicated to master students and biodiversity stakeholders, to improve their skills and critical thinking in advanced numerical methods for ecology, including species distribution modeling, population dynamics, sampling design and analysis of diversity indices.

- Environmental changes and ecological science : I contribute to several courses on global changes and environmental monitoring. My teaching is focused on the interactions between science and society through several lenses including epistemology and governance / spatial planning.
