Jan Phillipp Geißel

Dr. Jan Phillipp Geißel is a researcher at the University of Greifswald's Zoological Institute and Museum, within the Cytology and Evolutionary Biology department. His work focuses on larval physiology, thermal tolerance, and ecological impacts of climate change on marine species. He has conducted extensive research on invasive crustaceans like Carcinus maenas and Hemigrapsus takanoi, examining their adaptability to environmental stressors such as temperature and salinity. Geißel has presented at prominent conferences including the German Zoological Society and the International Crustacean Congress, and holds awards including the 2024 Best Talk Award. His research also explores latitudinal gradients in species distribution and potential Arctic expansions under climate change.

He is affiliated with the Society for Experimental Biology (SEB), German Zoological Society (DZG), and Association of Polar Early Career Scientists (APECS). Recent contributions include studies on larval thermal responses across Europe and Baltic Sea invasion dynamics. Geißel's work bridges physiology, ecology, and conservation, with a focus on marine systems' vulnerability to environmental shifts.
