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.
