Prof. em. Johannes Stähelin

Johannes Staehelin has been given the title of Professor of ETH in November 2002. He is a lecturer and he leads a research group at the Institute for Atmospheric and Climate Science since 1988.

Johannes Staehelin was born on August 16, 1949 in Basel, Switzerland. He studied chemistry at the University of Zürich. In his dissertation he studied the decomposition of ozone in water at the Swiss Federal Institute for Water Resources and Water Pollution Control (EAWAG) at Dübendorf, Switzerland. This work was awarded by the silver medal of ETH Zurich. Thereafter he was working at the Cooperative Institute for Research in Environmental Sciences (CIRES) in Boulder Co., USA, at the Agricultural Research Institute at Wädenwil (FAW) and at Ciba-Geigy Inc. in Basel. Since 1988 he is the head of a research group at the Laboratory of Atmospheric Physics at ETH Zurich. His research interest include long-term trend analysis of atmospheric ozone and atmospheric gas phase chemistry. The emissions of road traffic, air pollution at urban and remote sites and processes of the upper troposphere and of the lower stratosphere are studied.
