About

My main research topics concern the design of methodological approaches for the analysis of earth observations (images, local sensors, time series, ...). Applications concern environment (pollution, climatology, agriculture, ...)

I joined LETG-Rennes and OSUR in 2004 and between 2009 and 2012, I was in Beijing, China, working for LIAMA (Lab of Informatics, Automatics and Applied Mathematics), a lab composed of Chinese : CASIA (Chinese Academy of Sciences, Institute of Automation), Tsinghua University and European structures (INRIA, CNRS, INRAE, CIRAD, Groupe des Ecoles Centrales).

Since Oct. 2012 I came back to France as a CNRS Director of Research with LETG. I develop projects in collaboration with french and international related groups.
