Cosmogenic Nuclide Laboratory and Geomorphology Research Group

Allen Gellis



We have worked with Allen in very different environments, the arid Rio Puerco and the humid Susquehanna Basin. In both cases, Allen's interests and expertise in modern day sediment yield measurements has complimented well the long-term erosion rate data we generated with cosmogenic nuclides.
