Research

I integrate sedimentology, stratigraphy, and isotope geochemistry to reconstruct ancient environments within the context of secular and progressive tectonic, biospheric, and climatic evolution of the earth. The underlying theme of my research is to reconstruct paleoenvironmental change spanning from the late Proterozoic to the early Phanerozoic (~ 1200 to 500 ma) and to understand the interconnections between tectonics (i.e., supercontinental break-up and assembly), seawater chemistry and ocean redox, severe climatic fluctuations (including snowball Earth), and the origin and diversification of animals. This research is fundamentally field-based and geared around detailed geological studies of sedimentary basins that formed during this time.
