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.

Research Opportunities

  • Project 1. PhD, Summer 2018, Funding expected for tuition, fees, stipend, and research costs. Risk of earthquake - and landslide-generated displacement waves in eastern and Arctic Canada. Initiating in summer of 2018 with full funding expected, the PhD project will utilize cosmogenic isotope exposure dating, field mapping (Newfoundland, Labrador, Baffin Island), and numerical modelling to establish the risk of displacement waves for selected coastal communities.
