Environmental mass spectrometry and in-situ techniques

We study natural and anthropogenic contributions to the chemical composition of the atmosphere, interactions of human-made pollutants that have the potential to interact with plant-emitted trace gases, and the biogeochemistry of greenhouse gases. Novel environmental mass spectrometers, such as PTR-MS, PTR-TOF-MS, SRI-QTOFMS are used along with optical techniques to push the forefront of observational capabilities. The group develops and maintains biosphere-atmosphere exchange experiments, engages in ground based and airborne field campaigns and performs controlled laboratory experiments. In conjunction with process based models we aim  to study  atmospheric processes, to understand the composition and chemistry of earth's atmosphere, how it functions naturally, and how it is impacted by anthropogenic emissions and changing climate.
