Research
Geologic deposits in the world's lakes and oceans preserve unique records of past climate and ecosystem conditions. We pursue integrative approaches to investigating sedimentary deposits, including studies of modern environmental processes, the development of new techniques for decoding paleoenvironmental signals in lake and ocean sediments, and the generation and interpretation of new paleoclimate and paleoenvironmental datasets from key terrestrial and marine archives.
