Research

We study the epidemiology and management of tropical crop diseases, mathematically and numerically. We develop and analyse dynamical models describing plant-parasite interactions, in order to better understand, predict and control the evolution of damages in crops. We focus on pests and pathogens that affect major staple food and cash crops.
