Research Interests

Life changes chemical and physical properties of Earth since its emergence. Understanding involved processes and interactions to quantify or predict their effects, is what I, and many others, are interested in. My focus is on land-atmosphere interactions. Past work includes studies on soil organic matter, greenhouse gases, and radon as a tracer of atmospheric motions. More recently, I also became interested in the exchange of microorganisms between land and atmosphere. When lofted from leaf surfaces and transported by atmospheric motions, microorganisms can catalyse freezing of supercooled clouds and trigger precipitation events, re-depositing these organisms on new grounds. This kind of land-atmosphere interaction has implications on meteorology, but also on the distribution of ice-nucleating microorganisms, some of which are economically relevant plant pathogens.
