The Cosmogenic Nuclide Research Group advances the use of cosmogenic isotopes to quantify Earth surface processes. We develop and apply state-of-the-art techniques—including ¹⁰Be, ²⁶Al, ³⁶Cl, and in situ ¹⁴C—to reconstruct exposure histories, erosion rates, and landscape evolution across a wide range of geological and environmental settings. Our research spans timescales from thousands to millions of years and supports interdisciplinary collaborations in glaciology, geomorphology, tectonics, natural hazard assessment, and climate science.
Cosmogenic Nuclides
We determine surface exposure ages of landforms, surface erosion rates, and burial ages of sediments using the cosmogenic nuclides 3He, 10Be, 14C, 21Ne, 26Al, and 36Cl in different mineral systems to study landscape and human evolution on timescales of hundreds to millions of years. We host the NERC funded National Environmental Isotope Facility – Cosmogenic Nuclides (NEIF-CN).
