Research statement
My vision is to understand and quantify the processes by which anthropogenic emissions have changed the composition and levels of atmospheric pollutants and how these changes affect earth climate and public health. To gain insights into the mechanisms behind these processes and identify pollution sources, we develop and use new online and offline mass spectrometers, which analyze the atmospheric composition on a molecular level and down to 1 Hz time resolution. We deploy these instruments in the laboratory during simulation experiments and in the Field. We collaborate with global modelers and biochemist to quantify the overall impact of air pollution on climate and health.
