I study biosphere-atmosphere exchange processes and their influence on air pollution and climate change by developing instruments and conducting field campaigns, alongside laboratory experiments and modeling. One of my key research areas focuses on the sources of reactive nitrogen species (e.g., nitrogen oxides, nitrous acid, nitrate radical) and their role in regulating atmospheric oxidizing capacity. This, in turn, affects the lifetime of greenhouse gases like methane, the removal of primary pollutants such as nitrogen oxides and sulfur dioxide, and the formation of secondary pollutants, including aerosols and ozone. Another focus is quantifying greenhouse gas emissions from tropical rainforests and oceans through tower- and ship-based measurements (involved projects: Amazon Tall Tower Observatory and S/Y Eugen Seibold). These measurements help to better understand the carbon and nitrogen cycles and how ecosystems respond to climate change.
