Serge Guillaume got his PhD in Computer Science in 2001 and his habilitation thesis (HDR) in 2005, both from Toulouse University. He has been working for Irstea, a public National Research Institute of Science and Technology for Environment and Agriculture, for 30 years. He has been involved in fuzzy systems design and optimization for 20 years. He is now also interested in the design of decision support systems based on spatial data. This includes spatial modeling, e.g. zone delineation, and multicriteria decision making. Results of his work are implemented as open source software in the programs FisPro and GeoFIS .
