Mesozoic Sequence Stratigraphy
My MS and PhD work have dealt with sequence stratigraphic interpretations of Mesozoic carbonate environments. I enjoy using sequence stratigraphy as a framework to contextualize paleoecological trends, and as a tool to study environments that are not represented in modern geography.
Contextualizing Early Jurassic Iron Ooids
This project used sequence stratigraphic analysis to demonstrate iron-clay ooids found in carbonate facies from the Early Jurassic Sunrise Formation (Nevada) occurred as a condensation feature in backstepping parasequences, similar to iron ooids in siliciclastic systems.

Stratigraphic analysis of the Late Triassic Gabbs Formation
This project provided a stratigraphic framework for paleoecological studies conducted Nevada and demonstrates a decoupling of carbonate loss from facies changes vs. the onset of acidification in the latest Triassic.

Sequence Stratigraphy of the Gypsum Spring and Piper Formations
This analysis of the facies associated with the opening of the Middle Jurassic Sundance Seaway (Gypsum Spring and Piper Formations), was published from my Master’s thesis. The formations were studied in the Bighorn Basin of Wyoming.
