I am interested in understanding the interactions between tectonics, climatic processes and geochemical cycles on a range of time scales. I use radiogenic isotope geochemistry, in particular the rhenium-osmium (Re-Os) geochronometer, Sr and Nd isotopes combined with field-based mapping, sedimentology, stratigraphy and mineralogy to interrogate the rock record of critical transitions in Earth history.
My near term research interests are centered on three main areas: 1) refining Earth history records, especially Proterozoic tectonic reorganizations and eukaryotic diversification, 2) combining multiple geochemical proxies to provide better constraints on ice sheet dynamics over the last 5 million years, and 3) integrating the Re-Os geochronometer into the EARTHTIME organization and leading an international effort for inter-laboratory standardization.
If you are interested in learning more about these topics and joining the group I am always looking for motivated and interested students at the graduate and undergraduate level as well as post-docs. Please feel free to contact me directly.
