Francois Tissot
Francois Tissot
Professor of Geochemistry; Investigator, Heritage Medical Research Institute
Expertise
Isotope geochemistry, Meteorites, Evolution of the Solar System, Mass spectroscopy, Sample return missions
Profile
Tissot examines the isotopic composition of meteorites to understand the early solar system and how planetary bodies, including the Earth, evolved. Isotopes, which are twin versions of an element differing only in their number of neutrons, are also tracers of physicochemical processes at all scales, including galactic chemical evolution, planetary differentiation, and even human migrations.
