I study the evolution of continental collision zones using a combination of fieldwork, geochronology, and thermobarometry. I currently investigate the active Himalayan continental collision zone where partially-melted crust forms the backbone of the world’s highest peaks. I also examine ultrahigh-temperature (UHT) events that occur deep in the crust by studying the roots of an ancient mountain belt in southern Madagascar.
