Niklas H. Kitzmann

Doctoral Researcher, Scientist
Kitzmann

I am working as a scientist and science writer within the Planetary Boundary Science Initiative (PBScience) at PIK - a rapidly growing project with the ambitious goal of comprehensively assessing the health of our planet, by producing annual updates of the Planetary Boundaries framework. We presented our first Planetary Health Check Report to the public in September 2024, which can be downloaded at planetaryhealthcheck.org.

In parallel, I am writing my PhD thesis on a contagion- and network based understanding of Social Tipping processes in the sustainability context. Supervised by Dr. Jonathan Donges and Prof. Dr. Ricarda Winkelmann, my PhD project is aimed at combining insights from complex contagion, collective behavior, and social transformation research, and implementing both data- and simulation-based methods.

My PhD project has been 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 in the Whole Earth System Analysis Theme of the Earth Resilience Science Unit (ERSU), investigating the coevolution of natural and socio-economic subsystems of the Earth system in the Anthropocene. I am also a member of the copan collaboration at PIK, as well as the Earth Resilience and Sustainability Initiative (ERSI) partnership with Princeton University and the Stockholm Resilience Center (SRC).

Unsere Erde Unsere Freiheit Title Card screenshot.png

In the context of the German Year of Science (Wissenschaftsjahr 2024 - Freiheit), I helped produce a short film about the intersection between Freedom and planetary stability, called Unsere Erde, Unsere Freiheit. The film can be viewed on Youtube, and is being screened by a number of partners, within the Wissenschaftsjahr and beyond. If you are interested in showing the film, or co-operating in other ways, please reach out to my colleague Lotta Bergfeld and me.
