I investigate ice, water, and landscapes through the past and present: growth and decay of ice sheets and glaciers and their interactions with climate, dynamics of river systems, global sea level variability, and modern hydrologic and Earth-surface processes. I approach these questions through a combination of field observations, field instrumentation, and numerical modeling. My current research interests and projects include:

• The last deglaciation: ice sheet melt and associated proglacial lake development, fluvial geomorphic evolution, rapid sea-level rise, and impacts of meltwaer on climate
• Development of inexpensive and open-source instrumentation to measure modern hydrologic, ecologic, and geomorphic processes
• Open-source GIS algorithms to speed data processing and improve data--model intercomparisons
• Fluvial system response to climate and land-use change
• Lithospheric flexure as involved in glacial-isostatic adjustment and sedimentary basin backstripping
