About
Sedimentary rocks record processes that shape the evolution and habitability of Earth's surface environments. In the Earth Surface Evolution (ESE) group, we use a broad geological toolkit to explore the expression of these processes in the stratigraphic record, with the goal of characterizing and constraining the interfaces between tectonics, life, and climate throughout Earth history. Our research revolves around the improvement of (bio)geochemical models through the contextualization of sediment-hosted datasets with high-precision geochronology, physical sedimentology, mineralogy, low-temperature geochemistry, and detailed field observations at a variety of scales. Current interests include the evolution of the organic carbon and phosphorus cycles throughout Earth history, with an emphasis on elucidating drivers of phosphogenesis and the preservation and burial of biospheric organic carbon during periods of global change (e.g., the late Neoproterozoic and early Cambrian, the late Cretaceous, the Miocene, and the anthropogenic modern).
