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. To tackle these issues, we jointly supervise master and PhD students.
