Markus Egli is a Professor for Physical Geography at the University of Zürich (Switzerland). He is the head of the geochronology laboratories. His main research interests include landscape dynamics and processes (with a special focus on Alpine environments) using relative and numerical dating techniques and soil chemical and mineralogical aspects. A broad spectrum of dating methods is used to decipher landscape changes and geomorphic surface dynamics. Amongst the numerical methods are radiocarbon (14C) and 10Be exposure dating. Relative dating techniques include the investigation of soils, rocks, sediments and their mineralogy and chemistry. He is furthermore interested in the weathering mechanisms of soils (alpine to Mediterranean areas) and the ruling processes of chemical changes including human-influenced effects. Furthermore, he is guest professor at the Universities of Palermo (Italy) and the Zurich University of Applied Sciences (Wädenswil).
