Current Research

My research is broadly concerned with reconstructing Quaternary climate changes at the highest resolution possible using 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, tropical South America, and the midwestern US in order to reconstruct the spatiotemporal patterns and mechanisms of hydrologic variability. 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.
