My research aims to develop a better understanding of the dynamic co-evolution of life and the Earth system through studies generally focused on sedimentary archives. Field-based endeavors are supplemented with diverse analytical tools that include detrital sediment geochronology and geochemistry, carbonate isotope geochemistry, and biostratigraphy. I am particularly interested in understanding how lithospheric processes influence ocean–atmosphere chemistry, climate, and biospheric evolution. Active research projects: (1) investigating tectonic and environmental influences on animal evolution and mass extinctions; (2) Precambrian Earth System evolution with an emphasis on the Archean–Proterozoic and Neoproterozoic–Paleozoic transitions; and (3) broadly exploring tectonic influences on long-term carbon cycling and riverine-to-seawater chemistry. Field sites: India, Thailand, Philippines, Myanmar, Northern Greenland, Japan, North America, Australia, Argentina, China, South Korea, and southern Africa.
