Robert is an expert on the behavior of critical metals in magmatic-hydrothermal systems. His research combines experimental studies of the solubilities of metals in granitic melts and field studies of critical metal deposits. He was an Associate Professor at the Department of Earth and Environmental Sciences at the University of Waterloo from 1997 to 2010 and from 2010 to 2022 was the Robert Hodder Chair in Economic Geology at the Department of Earth Sciences at Western University in London, Ontario.
He obtained MSc and PhD degrees from McGill University. He was subsequently a post-doc at CNRS-CRSCM in Orléans, France and a Research Associate at the Bayerisches Geoinstitut, Bayreuth, Germany.
