Dr. Freja Chabert Østerstrøm

Biography

Freja Chabert Østerstrøm is a researcher at Aarhus University specializing in atmospheric chemistry. Her academic background includes a PhD in physical chemistry, an MSc in chemistry, and a BSc in environmental chemistry. Freja's research focuses on understanding atmospheric reactions and mechanisms, which have significant impacts on human health and the environment. She employs atmospheric modeling to compare experimental results with theoretical outputs, utilizing highly detailed chemistry box models and global Earth system models. This work addresses critical scientific questions, including the effects of indoor activities on air quality and the influences of volcanic eruptions on stratospheric ozone. Freja is currently involved in the Section for Atmospheric Emissions Modelling as part of the EU-funded ArcSolution project, where she models the atmospheric transport of long-lived pollutants such as PFAS in the Arctic, particularly in the context of climate change.
