John is a geochronologist and geomorphologist who specializes in the application of terrestrial cosmogenic nuclides (isotopes produced in rocks exposed to cosmic rays) to solve questions regarding: slip rates of faults in Tibet, USA, and southern central Andes; glacial history of Canada; rates of erosion and exhumation by landslides, streams, and glaciers; geoarcheology; and the influences of climate change, particularly the Pliocene-Quaternary change) on landscape change. Current field areas include Ellesmere, Devon, and Baffin Islands and the western Canadian Arctic archipelago, and southern South America.
