Niklas Kitzmann

Doctoral Researcher

Since October 2019, I have been working with Dr. Jonathan Donges and Prof. Dr. Ricarda Winkelmann on a contagion- and network based understanding of Social Tipping processes. Under the working title Social tipping dynamics for climate change mitigation and sustainability, my PhD project is aimed at combining insights from complex contagion, collective behaviour, and social transformation research, and implementing both data- and simulation-based methods. I am currently working on an analysis of the spreading of urban sustainability innovations on the global city network.

My PhD project is funded and organized in the context of the interdisciplinary Young Academy of Geo.X, the geoscientific competence network in Berlin and Potsdam. At PIK, my work is embedded within the COPAN collaboration's research on the coevolution of natural and socio-economic subsystems of the Earth system in the Anthropocene. I am also a member of the PIK FutureLab - Earth Resilience in the Anthropocene, and the RD1 working group Whole Earth System Analysis.
