André Chanzy is a senior scientist at the National Research Institute for Agriculture, Food and the Environment (INRAE) France. He received an engineering degree from INAPG (Institut National Agronomique Paris-Grignon) in 1986 and a Ph.D. in environmental science from the same University. He is currently head of the INRAE-Avignon University EMMAH research unit. He has a background in remote sensing and works on the microwave domain (active and passive) in order to assess soil water balance and evapotranspiration. His experimental work contributed to the design of the SMOS mission. More recently, his activity has been focused on global change and its impact on water resources and irrigation needs. He developed frameworks implementing crop models at the territory scale using remote sensing observations.
