Postdoctoral fellow at University of Oxford, part of the SalGo lab. Formerly at Doñana Biological Station (CSIC), Spain, studying the variation of ecological interactions.
My research focuses on ecological systems, lying at the intersection of theoretical and quantitative ecology. I humbly address one of the central questions in ecology: how ecological interactions shape the coexistence and long-term persistence of species. To explore this, I integrate data from field observations and experiments with theoretical frameworks using techniques from dynamical systems, complex networks, and computation.
