My research interests lie at the crossroads of several disciplines that can
generally be classified as watershed science. Specifically, my research program includes
development of water and sediment budgets, sediment transport processes and sediment
fingerprinting, linking fluvial and hillslope geomorphology, quantitative landscape
morphometric analysis, dissolved organic matter production and transport through
watersheds, light penetration in fluvial systems, and application of terrestrial
cosmogenic nuclides to study Earth-surface processes and long-term landscape change.
