Florian Ulrich Jehn is a Senior Researcher in Environmental Science, with a strong focus on food security, climate, and civilisational resilience. Florian did his Bachelor’s and Master’s degrees in Environmental Science, with a specialisation in hydrology and climate science, as well as studying soil science and ecology. This was followed by a Doctorate in Environmental Science and Hydrology at Justus Liebig University Giessen in Germany, with a focus on using large hydrological datasets to understand river behaviour on different scales.
In his first postdoctoral position, Florian studied extreme climate change and the evolution of the IPCC’s research focus over time. After this, Florian worked as a researcher and then as the data science lead at the Alliance to Feed the Earth in Disasters (ALLFED). This work focused on novel ideas that could potentially prevent global famine caused by catastrophic events. Florian’s research on this topic includes examining the feasibility of seaweed as a resilient food source after a nuclear war, exploring how planetary boundaries might interact with the effects of a nuclear winter, and investigating how global catastrophes impact food trade.
Currently, Florian is working at the FernUniversität in Hagen on the first accredited global catastrophic risk course in Germany. This course is meant to teach the main concepts and ideas of global catastrophic risk to a wide audience and will be made available as an open course after it has been tested and evaluated.
Aside from his research, Florian also enjoys science communication. He regularly writes a newsletter, [Existential Crunch], and gives talks and lectures to diverse audiences to raise awareness about the importance of food security and the impacts of climate and other global risks.
