My interests lie at the interface of geological, biological, and atmospheric sciences, and my research uses lakes and lacustrine organisms to investigate ecological and evolutionary dynamics and history. I specialize in the application of diatom analysis to questions of environmental change, and complement diatom-based reconstructions with geochemical and geomorphic approaches. My research also combines studies of lacustrine stratigraphic records with descriptive and experimental studies of modern lakes as models for interpretation of fossil sequences.
