Biography

I am research scientist at the CNRS based in Université Lyon 1 (Biometry and Evolutionary Biology Lab, UMR 5558).

I am a statistical ecologist (aka biometrician, biostatistician, quantitative ecologist, numerical ecologist, etc.). My work consists in developing novel statistical methods for analyzing biological data with a special emphasis on multivariate analysis and spatial statistics. I am mainly interested in understanding the role of multiple factors (e.g., species traits, environment) that influence the (spatial) structure of ecological communities and control beta diversity.

I am contributor/author of several software (freeware, open source) including the ade4 package for which provides statistical and graphical tools for the analysis of multivariate data.

The ade4 book is now available

This book introduces the ade4 package for R which provides multivariate methods for the analysis of ecological data. It is implemented around the mathematical concept of the duality diagram, and provides a unified framework for multivariate analysis.
