Jonathan Donges is a postdoctoral researcher who holds a joint position at the Stockholm Resilience Centre (as a Stordalen Scholar) and the Potsdam Institute for Climate Impact Research, within the Planetary Boundary Research Initiative (http://www.pb-net.org/). He studies planetary boundaries in the earth system from a complex dynamical system perspective. At Potsdam, he is co-head of the flagship COPAN (Coevolutionary Pathways) project. Jonathan is particularly interested in developing a hierarchy of modeling approaches, from conceptual to full complexity models, for understanding the global co-evolutionary dynamics of human societies and their geophysical-biological environment. His aim is to establish a system for the theoretical mapping of co-evolutionary space, including the characterization of attractors, basin boundaries, inaccessible domains, critical transitions and stability. Jonathan’s published research includes work on complex network theory, dynamical systems theory and time series analysis, with a focus on their application to our understanding of past and present climate variability and its interactions with humankind on Planet Earth. Jonathan holds a PhD in theoretical physics from Humboldt University in Berlin and a diploma degree in physics (MSc equivalent) from the University of Potsdam. Before coming to the Stockholm Resilience Centre, he studied physics, mathematics, environmental science, and oceanography at the University of Potsdam, the University of California San Diego, Scripps Institution of Oceanography in La Jolla, and the University of Bonn. He has also spent time in the field conducting paleoclimatological and speleological research in Meghalaya, North-East India.
