I am a researcher working at CIRAD in the AMAP lab in Montpellier, France. I am specialized in Functional-Structural Plant Modelling (FSPM), and my research interests include ecophysiology, environmental physics, tree architecture, computer models and agronomy.
I am the co-manager of the FSPM theme of AMAP along with Jean Dauzat. I work mainly on the ARCHIMED platform but I am also a member of the EPS, the team of the STICS project (referent for the intercrop version).

The DynACof model was designed to model coffee agroforestry systems and study the trade-offs to e.g. optimize the system facing climate changes. The model simulates net primary productivity (NPP), growth, yield, mortality, energy and water balance of coffee agroforestry systems according to shade tree species and management. Several plot-scale ecosystem services are simulated by the model, such as production, canopy cooling effect, or potential C sequestration. DynACof uses metamodels derived from a detailed 3D process-based model (MAESPA) to account for complex spatial effects, while running fast. It also includes a coffee flower bud and fruit cohort module to better distribute fruit carbon demand over the year, a key feature to obtain a realistic competition between sinks. The model was parameterized and evaluated using a highly comprehensive database on a coffee agroforestry experimental site in Costa Rica. The fluxes simulated by the model were close to the measurements over a 5-year period (nRMSE~=~26.27 for gross primary productivity; 28.22 for actual evapo-transpiration, 53.91 for sensible heat flux and 15.26 for net radiation), and DynACof satisfactorily simulated the yield, NPP, mortality and carbon stock for each coffee organ type over a 35-year rotation.
I am the author of the collaborative free open-source book “Le compagnon de l’utilisateur R”. This book is a side project that I work on during my free time, so this is still in progress. It is a book about how to use the R progamming language along with RStudio for data science, graphics, reproducible research and more, using state of the art tools such as
It is in french only for the moment, but will be translated to other languages hopefully.
