I am a physicist studying complex adaptive systems, with a special interest in understanding how ecosystems react to global change. I am a visiting postdoctoral fellow at ISEM, collaborating with Dr. Sonia Kéfi to explore the nature of abrupt transitions in complex networks of many interacting species. Understanding the underpinning mechanisms of these so-called « regime shifts », with small perturbations able to induce large changes towards deteriorated ecosystem states, represents a necessary step in the face of climate emergency. To explore this, my interdisciplinary approach takes advantage of current mathematical developments in statistical physics and complex networks combined with in-silico ecosystem simulations and data of community-level shifts.
