My research is in clastic sedimentology with an emphasis on diagenesis. I combine traditional techniques such as field methods, petrography, and X-ray diffraction with novel ones such as QEMSCAN and detrital zircon geochronology to solve problems using new approaches. My two principal research foci are: 1. paleogeography and basin evolution, and 2. astrobiology and Mars sedimentology using terrestrial analogs.
- Magmatic Intrusions into Sulfur-rich Sediments: An Exposed Potential Subsurface Habitable Environment as an Analog for the Martian Crust
- Basin reconstruction of the Central Colorado Trough
- Distinguishing biotic from abiotic precipitation mechanisms: Ten Mile Graben cold spring system
- Constraining conditions for habitability in diagenetic environments
- The origin and persistence of diagenetic jarosite and alunite in Jurassic rocks on the Colorado Plateau
