Since April 2024, I am a shared Post-Doctoral Researcher between the Potsdam-Institute for Climate Impact Research and the Center for Critical Computational Studies. Here, my research focuses on interacting tipping elements in the Earth system, ranging from elements in the physical climate system to global ecosystems. I investigate how the stability of these particularly vulnerable components are affected by human activity and might endanger the overall stability of the Earth system. I am also interested in the effects of social sustainability transformations on the risk for dangerous climate tipping events.
For that purpose, I am working with models informed by complex dynamical systems and network science, as well as Earth system models of intermediate complexity (EMICs).
