My research program examines the geologic and biogeochemical mechanisms that have maintained Earth's biosphere and habitability over its history. To this end, the sedimentary shell is an invaluable archive, recording ~3.8 billion years of Earth surface evolution. My research is grounded in field observations of sediments - particularly of carbonates, which simultaneously record information about the chemical, physical and biological conditions in which they formed. Field campaigns are supplemented by the development of geochemical data sets (e.g., δ13C, δ44Ca, δ26Mg, trace elements). Complementary to these approaches, I also unravel Earth history at a larger spatial scale by working with Macrostrat, a database that describes the spatial-temporal distribution of rocks in the upper crust. Working also with the digital library GeoDeepDive, I use these databases to constrain continent-scale patterns of sediment accummulation and preservation, and explore the attendant implications for Earth system evolution.
