Professor
Sebastian Diehl is a Professor at Umeå University's Department of Ecology, Environment and Geoscience. His research focuses on mathematical modeling of aquatic ecosystem dynamics, with particular emphasis on consumer-resource interactions and climate change impacts on northern lake ecosystems. Current affiliations: Umeå University (Department of Ecology, Environment and Geoscience) Previous affiliations: Ludwig-Maximilians-Universität München (Professor of Aquatic Ecology) Academic background: Biology undergrad from University of Göttingen, PhD in Animal Ecology from Umeå University (1994) Research interests center around aquatic ecosystem dynamics in response to environmental change, including: Climate change effects on lake ecosystems (temperature and terrestrial nutrient inputs) Mathematical modeling of consumer-resource interactions Benthic-pelagic coupling in nutrient and energy flows Phytoplankton-zooplankton dynamics under environmental stressors Trophic interactions in stream and lake systems Stoichiometric constraints on ecosystem function His recent publications (2025-2020) demonstrate an integrated approach combining mathematical modeling with experimental validation through field studies and lab experiments, focusing particularly on: Climate-induced regime shifts in lake ecosystems Stoichiometric mismatch in warming systems Functional response modeling Vertical niche partitioning in plankton Resource acquisition trade-offs Browning impacts on primary producers Administrative roles include: Final examiner for PhD education Chair of Umeå Marine Science Centre advisory council Steering group member of Integrated Science Lab (IceLab)
