Specialization in sedimentary geochemistry with applications to paleoceanographic and global systems analysis.  Research is directed along three broad themes: Environmental change at the Permian/Triassic boundary, the relationship of land plant evolution to weathering rate changes and global events during the Middle to Late Devonian, and the development of trace-metal redox proxies to study paleomarine systems.
