Alison Denn

Alison used in situ cosmogenic nuclides to understand how landscapes develop over time. She came to UVM in 2014 supported by the Susquehanna Shale Hills Critical Zone Observatory. Her research investigated erosion rates and residence times of landforms south of the last glacial boundary in Pennsylvania, including the enigmatic boulder field at Hickory Run State Park.
