- The depositional, paleoclimatic, and tectonic setting of sedimentary basins based on sedimentologic, stratigraphic, and structural field work, and integration of geochronologic, geochemical, isotopic, paleomagnetic, and geophysical studies
- The assembly and breakup of Precambrian supercontinents, and the consequent effects on the global sedimentary record
- Intercontinental correlation of 2.5 - 2.0 Ga successions, with emphasis on Earth's first global glaciations and the appearance of free oxygen in Earth's atmosphere

- Natural hazards and use of the stratigraphic record to define recurrence intervals for potentially catastrophic events
