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 rhenium-osmium (Re-Os) geochemistry and geochronology and Platinum Group Element geochemistry 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 geochemical proxies to provide better constraints on ice sheet dynamics over the last 5 million years, and 3) employing radiogenic isotopes as tracers of crustal-mantle processes.
