My research uses field geology, petrology, geochemistry, and geochronology to read Earth’s history from rocks and minerals—especially garnet and accessory minerals such as zircon, monazite, and allanite. Current themes span Himalayan mountain building and geohazards (including NSF-supported work on Himalayan lineaments), extensional tectonics and transfer zones in western Anatolia, extrusion and critical-mineral systems in the Western Carpathians, radiometric dating of early land plants and animals, and impact chronology in North America. Students work with me in the field, in the lab, and on data interpretation at undergraduate and graduate levels.
