Vision

Our vision is the understanding of atmospheric chemical processes by which emissions transform and perturb atmospheric oxidation conditions and form secondary pollutants, like aerosols and ozone. This is critical for assessing the environmental impacts of different emissions and the consequences for air quality, climate and human health.

Mission

Our mission is to develop analytical techniques, simulation reactors and numerical tools for the characterization of the aerosol molecular composition, sources, and formation pathways in diverse environments ranging from the Arctic to polluted atmospheres like China and India. We simulate these environments in state-of-the-art smog chambers at PSI and at CERN, as well as using mobile reactors. By implementing detailed molecular-level experimental data in box models, we derive simple parameterizations that can be integrated in regional air quality models to estimate the environmental impacts of different pollution sources and formation pathways.
