My research activities concern modelling the dynamics of ecological systems, from both theoretical (study of prey-predator or host-parasitoid systems) and more applied (forest, epidemic, fishery) perspectives. I use methods coming from the mathematical (dynamical systems) and computer (cellular automata network, individual-based models) sides of ecological modelling. Since 2003 I am employed by the Institut de Recherche pour le Développement (IRD) and presently in the MARBEC research unit.

My Ph.D. fitted into a new project aiming at developing one or several models that enable to answer questions concerning forest communities biodiversity, in particular on the factors which favour their species richness. My personal contribution to this project was to study to what extent simulation models of forest dynamics could give insights to these questions. My work showed that before using such models for prediction, there were several difficult stages to pass through: choice of the model, choice between different approaches of spatialisation, sensitivity analysis of the parameters and initial conditions, validation towards field data.

The correspondence between the mathematical model dynamics (red curve on the images below) and the computer model dynamics (blue, yellow, black, green and grey curves) improves as the neighbourhood size increases (4, 8, 12, 24 et 48 neighbours on the images below).
