T. Kurtis[1] (Kurt) Kyser (October 7, 1951,[2] Montana, U.S. — August 29, 2017, Bermuda) was an American and Canadian geologist and geochemist, Fellow of the Royal Society of Canada, professor of the University of Saskatchewan and Queen's University, founder and director of the Queen's Facility for Isotope Research (QFIR).
Kyser served as a president of the Mineralogical Association of Canada (between 2006 and 2008) and as an Editor-in-Chief of the journal Geochemistry: Exploration, Environment, Analysis (GEEA).
[3] After completing a post-doctoral fellowship at the United States Geological Survey in Denver and a NATO post-doctoral fellowship at the University of Paris, Kyser returned to the North America to work at the University of Saskatchewan (Canada) as an assistant professor; in 1989 he was made a full professor.
[3] The bulk of his research focused on application of isotopes, uranium in particular, to mineral exploration and environmental geochemistry, although he was influential on multiple other science disciplines.
During last years of his life he served as the Editor-in-Chief of the Geological Society of London's journal Geochemistry: Exploration, Environment, Analysis.
