Boudreau's expertise lies in origins of igneous layering: Numerical modeling of postcumulus processes such as crystal aging and compaction and how they can give rise to the variety of features observed in igneous layering. Petrogenesis of platinum-group element (PGE) deposits in layered intrusions and associated work on degassing of crystal assemblages and evidence for the mixing of igneous fluids with liquid + crystal assemblages.
