Luc Doyen, Doctor in applied mathematics, has received an education in control theory, optimization and mathematical economics. He currently holds a permanent position of Director of Research at the CNRS (Centre National de la Recherche Scientifique), where he is especially involved in bio-economic modeling, viable management of biodiversity and mathematics of sustainability. He is now affiliated to the Gretha (Research Group Theoretical and Applied Economics) at the University of Bordeaux after spending 10 years in a laboratory dedicated to ecology and conservation biology at the Museum of Natural History in Paris. A book « Sustainable management of natural resources models and methods » recently published by Springer and 50 publications in international peer-reviewed journals emphasize the mix between the applied and theoretical dimensions of his research activity and its inter-disciplinary nature balancing ecology, environmental economics, and modeling. The applied component of his research relies on contracts and grants pointing out the transfer of the theoretical results toward national or international institutions such as INRA, IFREMER, CGIAR, CSIRO regarding the management of agriculture, fisheries and biodiversity. He is reviewer of numerous international journals and has participated to various national and international committees for the evaluation of research. Luc Doyen also organized in 2013 a quarterly thematic program at IHP (Institut Henri Poincaré) entitled "mathematics of bio-economics" in the framework of the international event MPE 2013 (Mathematics of Planet Earth 2013). Its numerous teachings (Masters, Engineering schools) and supervisions (Post-doc, Ph-D, master, ...) also highlight the interdisciplinary feature of his activities at the interface between mathematics, computer sciences, economics and ecology.
