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 four main areas: 1) refining Earth history records, especially Proterozoic tectonic reorganizations and eukaryotic diversification, 2) combining geochemical proxies with microfossil and sedimentological analyses to provide better constraints on ice sheet dynamics over the last 5 million years, 3) understanding hydrocarbon systems and ore genesis through the use of geochronology and geochemistry, and 4) 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.
