Fisheries dynamics modeler, I graduated from the University of Rennes 1 in Applied Mathematician specialized in probability, statistics and modeling (Magistère de Mathématiques - 1994). I did my PhD at the INRIA from 1994 to 1997. I worked on Markovian models applied to high dimensional problems. Since 1998, I work at Ifremer, first in Nantes at the laboratory of mathematics applied to fisheries and aquaculture resources and then at the laboratory of ecology and models for fisheries (UMR DECOD) and since January 2023 at the UMR MARBEC in Sète. My main research areas are fisheries dynamics modeling, statistical methods for fisheries data analysis, methods of analysis and exploitation of complex models for decision support including quantitative approaches (sensitivity and uncertainty analysis, calibration) and transdisciplinary qualitative approaches (foresight, participatory approach, art-science). In 2009, I obtained the French habilitation to supervise research. In addition to supervising students, engineers and researchers, I have been and am responsible for several research projects (currently, FFP MACCO project  and the  Science and society MIMI project). I am vice-president of the Scientific commission  "Sciences des systèmes écologiques" of IRD. I am also member of several steering committees of research networks (e.g. réseau mexico and l'IUML) and member of the Administration committee of the French "learned society" Association Française d'Halieutique. I have published 57 scientific articles (A-level), co-edited a book on sensitivity analysis for complex models, and published 7 book chapters.
