Research Interests

Currently I am pursuing several areas of research, all of which involve isotope ratio variations in marine and terrestrial records.  My focus is on how isotope and trace element tracers can be used to understand the relationship between past climate change (on Quaternary and even longer timescales) and past oceanic biological productivity, deep-ocean circulation, and patterns of continental aridity and hydrology based on past riverine discharge and eolian fluxes to the ocean.  By concentrating on the geochemistry of marine sediment archives, I aim to make a significant contribution to the study of climate forcing and response mechanisms.  Understanding these mechanisms will help address a critical problem faced by climatologists.  We have direct observational data on the chemical and physical parameters of the ocean for only about the past 50-100 years. In order to understand the impact of large-scale anthropogenic release of greenhouse gases into the atmosphere, and because the ocean plays such an important role in the global carbon cycle, we need to have empirical evidence from sedimentary proxies in order to understand better climate-related atmospheric/oceanic processes.
