Dray Stéphane

Dray Stéphane is a Senior Research Scientist (CNRS DR2) at Université Claude Bernard Lyon 1, affiliated with the Laboratoire de Biométrie et Biologie Evolutive (LBBE, UMR 5558). His research focuses on statistical ecology, combining multivariate analysis, spatial statistics, and computational tools to address ecological questions. Key areas include community ecology, population dynamics, and the impact of biotic/abiotic factors on species distributions.

Dr. Dray holds a PhD in Biometry (2003) and a Habilitation (2016) from Université Lyon 1. He has extensive postdoctoral experience, including a stint at Université de Montréal. His work bridges statistics and ecology, with notable contributions to software development (e.g., ade4, adespatial), which are widely used for ecological data analysis.

His research emphasizes innovative statistical methods for analyzing ecological networks, spatial patterns, and species interactions. Recent work explores applications in camera trap data analysis, phylogenetic comparative methods, and the calibration of deep learning models for wildlife monitoring.
