Dr. Marie Weiss is working at the French National Institute of Agronomic Research (INRA), in Avignon, France. Her main research interest is the development and the validation of algorithms for the estimation of biophysical variables such as leaf area index (LAI) and fraction of absorbed photosynthetically active radiation (fAPAR) from remote sensing data. She has been working on the development of operational products from European satellites (VEGETATION, PROBAV, SENTINEL2).  She was also involved in designing instruments and softwares for close range sensing (e.g. CAN-EYE, PASTiS, SCANAREA). More recently, she is focusing on very high resolution sensing by UAVs and mobile robots for applications in phenotyping contexts.  She is co-Editor in Chief of Remote Sensing of Environment and  co-leader of the CEOS (Committee on Earth Observation Satellites) LPV (Land Product Validation) subgroup on fAPAR since 2017
