He is currently on a leave of absence to work as Chief Geologist of Toronto-based Noront Resources Ltd. His research is largely oriented toward understanding the genesis of magmatic ore deposits, using inputs from igneous and hydrothermal geochemistry, extensive field work, and experimental petrology. A major focus of his work in recent years has been the use of platinum-group elements as tracers to illuminate the genetic processes that form magmatic ores, spanning the range from melting and magma transport to phase separation and collection.
