Alison Denn
Alison used in situ cosmogenic nuclides to understand how landscapes develop over time. She came to ¶¶Òõ̽̽ 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.
