The aim of my current research is to improve our understanding how we can best model ecosystems and their interaction with human activities. We know that ecological and human systems are 'complex'; from the one hand, we need to address this complexity, accounting for multiple phenomena interacting with one another, chaotic dynamics and large number of degrees of freedom. From the other hand, we need to simplify our analysis as much as possible, to make it manageable. Finding this sort of workable compromise is what most of my research is about. My research focuses mostly on three areas:
