Theme MPPM - Maths for Plants and Plants for Maths


Statistics, mathematical modelling and numerical simulations are useful methods and tools to study complex systems in biology, agronomy and ecology. Among these systems, our focus is on natural plant populations and crops in tropical environment, related to global changes. We also study plant-insect interactions.
In most of these systems, the biological, agronomical or ecological processes are not necesseraly well known. Thus, according to the (initial) scientific question, different mathematical approaches are possible. Among them, mathematical modelling allows not only to represent (formalize) and simulate (very) complex systems, but also to study deeply the behaviour of these systems (based on theoretical results).
However, if mathematics are widely used in many areas of life sciences, they are, paradoxically, underused (except statistics) in plant area.

Scientific objectives

The MPPM theme aims to use (common or new) theoretical and numerical approaches, as well as to develop/propose analytical tools.
Our objective is to focus on the dialogue between thematic issues and the exploration of new modelling formalisms.

Expected results

  •  Mathematical tools/methods/approaches that allow to go further in the study of plants and their interactions with the environment.
  •  Fundamental and applied reseach in Mathematics in Plant area
