Dr. Stefan OsterwalderAssistent / PostDoc
My research interests include the atmospheric chemistry, transport and biogeochemistry of trace gases, in particular mercury (Hg), and the quantification of their surface-atmosphere exchange using micrometeorological methods. My primary research covers a range of issues relevant to terrestrial and marine Hg cycling, from innovating new flux measurement systems (REA, Eddy Mercury), and leading comprehensive field campaigns to analysis of high-resolution data and process modeling. Within the framework of my latest studies at IGE, University Grenoble Alpes, France (SNF Postdoc.Mobility Fellowship), I have addressed Arctic Hg pollution by investigating Hg deposition and re-emission between the Arctic Ocean and the atmosphere.
