Kaspar Hegetschweiler

from Wikipedia, the free encyclopedia

Kaspar Hegetschweiler (born June 12, 1954 in Zurich ) is a Swiss chemist . From 1996 to 2020 he was Professor of Inorganic Chemistry at Saarland University .

Life

After graduating from high school in 1973, Hegetschweiler studied chemistry at the ETH Zurich until 1979 . He then worked for a year as a lecturer in chemistry at several grammar schools in the canton of Zurich and obtained the diploma for higher teaching qualifications (grammar school). From 1980 to 1984 he worked on his dissertation in Zurich on the subject of polyalcohol complexes of Fe (III) .

This was followed by a year-long postdoctoral fellowship with Paul Saltman at the University of California, San Diego , where he worked in the field of bioinorganic chemistry. He then worked until 1988 as the main teacher for chemistry and physics at the Interlaken grammar school.

From 1988 to 1993 Hegetschweiler was senior assistant at the Department of Environmental Sciences at the ETH Zurich, where he completed his habilitation from 1993 to 1995 at the Laboratory for Inorganic Chemistry. In 1995 he was appointed private lecturer . His habilitation thesis was on 1,3,5-triamino-1,3,5-trideoxy-cis-inositol and alkylated derivatives, a new class of remarkably versatile ligands .

In 1995 he went to the Research School of Chemistry of the Institute for Advanced Studies at the Australian National University in Canberra as a Visiting Fellow , where he carried out joint research with Alan Sargeson .

On January 1, 1996, he took up a C3 professorship for inorganic chemistry at Saarland University in Saarbrücken, where he was vice dean of the chemistry department from 1998 to 2000. In 2001, Hegetschweiler began a research semester at Syracuse University in New York State with Jon Zubieta . Before he accepted the call for a C4 professorship for inorganic chemistry at the Saarland University in 2004, he had already rejected calls for professorships in Potsdam and Bielefeld. From 2004 to 2007 he was dean of the Faculty of Science and Technology III at Saarland University. Hegetschweiler retired on April 1, 2020 and has been a senior professor ever since .

The focus of Hege sealed hamlet research lies in the development and characterization of organic ligand for the selective complexation of certain metal - cations . Hegetschweiler's group cooperates in application-related projects in this field with industrial companies such as Novartis , Evonik Industries and Bayer AG . There is also a cooperation with the National Institute of Standards and Technology .

Hegetschweiler is the author or co-author of over 150 articles in international journals.
