My research broadly examines plate tectonic processes over the breadth of Earth history. I investigate the tectonic evolution of continental lithosphere, particularly processes related to the accretion of terranes as recorded by igneous, metamorphic and sedimentary systems, the tectonic assembly of North America, and the evolution of sedimentary basins as captured by detrital heavy mineral suites. I utilize accessory mineral phase U-Pb geochronology and geochemistry, as well as traditional whole-rock geochemistry and petrography to investigate these problems. My expertise focuses on zircon, but I am expanding my tool kit to include other minerals, such as titanite, monazite, rutile and garnet to integrate into comprehensive research projects.
Active project: Origins and evolution of the Marshfield terrane of west-central Wisconsin as revealed by zircon U-Pb geochronology and geochemistry.
Active project: Provenance of Borden Group sandstone and siltstone units, eastern Illinois Basin.
