The radio feature from Deutschlandfunk (in German) provides insights into the research of Frank Keutsch, Stonington Professor of Engineering and Atmospheric Science at Harvard University and TUM-IAS Hans Fischer Senior Fellow. He combines laboratory and field experiments with instrument development to investigate fundamental mechanisms of anthropogenic influence on atmospheric composition within the context of impacts on climate, humans and the environment.
