Roman DiBiase’s research focuses on quantifying the mechanisms of erosion and sediment transport responsible for shaping Earth’s surface and applying this insight to problems ranging from post-wildfire erosion to landscape evolution. He is motivated by the challenge to develop surface process models that satisfy both modern observations and longer-term geologic constraints. Such a mechanistic approach is necessary to better predict landscape response to changing climate and land use conditions, mitigate natural hazards, and understand the dynamic interactions between surface and deep Earth processes. They investigate these problems using fieldwork, topographic and photogrammetric analysis, cosmogenic radionuclides, and modeling.

Alison Duvall is a geologist who studies how mountains are built and how the landscape responds to these processes. More specifically, she looks at how plate tectonics, erosion, and climate all work together to shape the Earth’s surface across both space and time. In addition to mountains, she investigates what happens when two blocks of Earth’s crust slide past each other (called strike-slip faulting), changing hill slopes, river channels, and other features of the landscape. Because they are often continuous for long distances, strike-slip faults are especially prone to large earthquakes, but measuring their activity is hard. Duvall hopes to develop new ways of both recognizing and analyzing fault activity directly from surface processes.
