Teaching and Clinical Areas
Dr. Koester has supervised three post doctoral fellows, 10 PhD
students, six Masters/Diploma students, a number of technicians and
numerous undergraduate students. He is experienced in teaching
lectures, seminars and practical courses at all university levels in
the areas of microbiology, genetics, biochemistry, molecular biology
and environmental sciences with teaching duties at Universities in
Germany and Switzerland, and now at the University of Saskatchewan.
Dr. Koester currently holds the “NSERC/Bioniche Associate Industrial
Research Chair in Vaccines to Reduce Food and Water Contamination” with
the long-term goal to develop effective intervention strategies in
order to reduce the amount of bacterial pathogens in animals used for
food production. He is interested in various aspects of food and water
safety, virulence mechanisms of pathogenic bacteria and host-pathogen
As a post-doctorate fellow of the German Science Foundation (DFG), he
investigated bacterial vitamin B12 uptake in the laboratory of
Professor R.J. Kadner, University of Virginia, Charlottesville, USA. As
well, he worked as an assistant professor on bacterial iron transport
at the University of Tübingen, Germany.
He was a visiting scientist (Cantarini Fellowship of the Institut
Pasteur and Fellowship of the CNRS) at the Institut Pasteur, Paris,
As a senior scientist, he was leading the group 'Drinking Water
Microbiology', at the Swiss Federal Institute for Environmental Science
and Technology (EAWAG), Dübendorf, Switzerland. There he studied
survival strategies of bacteria in the environment, molecular detection
methods for microbes, and metal homeostasis in unicellular green algae.
From 1999-2003 he served as Swiss Delegate and “invited expert” at
various events related to safe drinking water of the Organisation for
Economic Co-operation and Development (OECD) and the World Health
