Researcher at AMAP - CIRAD

CIRAD

Biography

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).

Interests

  • Structure-Function interaction
  • Ecophysiology
  • Environmental physics
  • LiDAR
  • Process-based Modelling
  • R language
  • Julia language

Book

Le compagnon de l’utilisateur R.

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 tidyverse, ggplot2, plotly, data.table etc…
It is in french only for the moment, but will be translated to other languages hopefully.
