Current Research

My research is broadly concerned with reconstructing the atmospheric component of late Quaternary climate changes at decadal resolutions using high-resolution lake sediment archives. Although my work addresses a range of environmental questions, I am particularly in interested in the intersection between climate change and water resources and the impacts on natural and anthropogenic systems.  My current projects are focused on developing new hydroclimate records from Tibet and tropical South America in order to reconstruct the spatiotemporal patterns and mechanisms of mean state changes in these major monsoon systems. Variations in these systems directly influence the lives of millions of people that rely on monsoon rains for fresh water. Methodologically, I combine field-based and modern process investigations with quantitative down-core multi-proxy analyses that integrate sedimentology, stable isotope and elemental geochemistry, geophysics, and isotope-enabled hydrologic modeling.
