Jan Petzold is Science Officer at the TSU and has expertise in sustainable resource management, community resilience, and adaptation to climate change. Jan will be primarily engaged in questions that refer to the IPCC special report on climate change, desertification, land degradation, sustainable land management, food security, and greenhouse gas fluxes in terrestrial ecosystems (SR2). Moreover, his special focus lies on human-nature interactions in coastal regions and small islands. He holds a PhD in geography from the University of Hamburg where he was affiliated with the Cluster of Excellence "Integrated Climate System Analysis and Prediction" (CliSAP). For his PhD research, Jan analysed the potential and limitations of social capital for adaptability to climate change on the Isles of Scilly (UK). Further research projects included fieldwork on various islands, such as Helgoland (Germany) and The Bahamas.

Katja Mintenbeck

Science Officer

katja.mintenbeck@ipcc-wg2.awi.de

Katja Mintenbeck, marine ecologist and Science Officer in the TSU, has long-standing experience in studies on direct and indirect effects of environmental changes on marine living communities. Her research focused on the impact of disturbances and fisheries on fish and benthos communities, trophic interactions, food web structure and stability, the impact of climate change on communities and the vulnerability of key fish species. Besides, she worked on environmental impact assessments in a large European project. Recently, she started extending her scientific approach identifying global pattern in species' vulnerability to ocean acidification using meta-analysis. Her work took her to many expeditions to the Antarctic, the Arctic and the North Sea, and the results of her studies are published in several book chapter and journal articles.
