What can cosmogenic and radiogenic nuclide measurements reveal about surface exposure, erosion, and planetary histories? The research applies stable- and radio-nuclide measurements to Quaternary landform evolution, cosmochronology, hydrology, and atmospheric processes. The group develops and improves techniques to measure new cosmogenic nuclides and enables expanded geochronologic constraints. Researchers operate and direct the PRIME Lab to produce cosmogenic nuclide data used for exposure dating and erosion-rate studies. Laboratory measurement development is combined with field sampling campaigns to address timescales of surface and planetary processes.
