My research

Between fundamental and operational research, my work fits into the major contemporary issues of biodiversity erosion. I try to understand the effects of human activities on aquatic ecosystems with, as a medium-term objective, the establishment of operational tools to help with conservation, management or ecological restoration.

Currently, I am interested in the potential effects exerted by flow barriers (dams, sills, dykes, etc.) on the hydromorphology of rivers in France and the taxonomic and functional responses of biological communities (diatoms and benthic macro-invertebrates, fish) in the face of habitat fragmentation.

I use Random Forest type modeling methods based on standardized national data acquired by different national environmental actors.

Expertises

My multi-scale approach to hydrographic networks allows me to use my skills in graph theory and geomatics (the Dendritival Hierarchical Network paradigm). I use learning models such as Random Forest and Gradient Forest to model complex systems without a priori, by integrating indicators of biodiversity and pressures. My multivariate statistics skills are depolyed to understand the ranking and prioritization of pressures in watersheds. Finally, my knowledge and my various discussions with the actors allow me to have an objective opinion on the complexity of hydrosystems (pressures of anthropic origins, meta-communities, physiographic controls of watersheds, hydromorphological evolution of hydrosystems, hierarchical spatial framework , ...), useful from an operational management perspective.
