My research focuses on environmental and climate changes across critical transitions in Earth’s history. In particular, I utilize an integrated field, petrographic, and isotope-geochemical approach to study the origin of carbon isotope anomalies and unusual oceanographic changes at the dawn of animal life and across the major Paleozoic greenhouse−icehouse transitions. Through comparative study of the Neoproterozoic to Paleozoic sedimentary archives in the Great Basin of western U.S. and in other continents such as South China, my research attempts to better understand the causal relationships between carbon isotope excursions, ocean redox changes, sea-level changes and biotic innovations.
