Doctoral Researcher

Marie Hemmen is a doctoral researcher at IRI THESys and the Potsdam Institute for Climate Impact Research (PIK), funded by the Deutsche Bundesstiftung Umwelt (DBU). Her research focuses on the impacts of high temperatures on global agricultural production. During her PhD, she develops a method for enhanced heat stress representation in process-based crop models and implements the approach in the dynamic global vegetation model LPJmL. By applying the advanced model, she then analyzes climate change impacts, and especially high temperature impacts, on global crop yields and evaluates different agricultural adaptation measures regarding their potential to mitigate heat stress induced yield reductions.

Marie completed both her BSc. and MSc. in Biophysics at Humboldt-Universität zu Berlin. After her studies, she worked as a research associate at the Institute for Energy and Environmental Research Heidelberg in the department Biomass and Food.
