My research focuses on sedimentary processes in modern and ancient basins.  One strand of my research involves deciphering the tectonic record contained within a stratigraphic section by integrating sedimentologic analyses, geologic mapping, detrital geochronology (U-Pb and Hf isotopes), mudstone  geochemistry (rare earth elements), and heavy mineral and petrographic provenance analyses.  Research areas have included forearc and backarc basins in south-central Alaska, the Cordilleran foreland basin in southwestern Montana, Paleozoic cratonic basins in the Midcontinent, the Miocene Apennine foreland basin in Italy, and the Cretaceous Neuquén basin in Argentina. More recently, I have started investigating geochemical proxies in marginal marine mudstones as proxies for environmental conditions.
