My students and I study the sedimentary record to understand the roles of tectonics and climate in controlling basin subsidence and filling. The tools we use are drawn a number of geology sub-disciplines including basin analysis, sedimentology, regional tectonics, structural geology, stable isotope geochemistry, magnetostratigraphy, radiogenic isotope geochronology and thermochronology. Our research focuses on testing theory predictions using field-based relationships, laboratory analyses, and numerical modeling approaches.
One of my recent interests includes the basin record of the onset of orogenesis and subsequent changes in basin geometry based on quantitative multi-proxy sediment provenance and dispersal reconstructions.
I am also pursing the stable isotopic record of elevation changes in high-elevation terranes including the Tibetan Plateau and Peruvian Altiplano. Surface uplift can result in local and regional climate and environmental changes which can also impact the depositional and stable isotope systems. In order to accurately understand the drivers behind observed changes in sedimentology and stable isotope systems, we seek also to understand changes in environment and climate through time.
