Areas of Interest

Teaching Philosophy

Problem-solving and experiential learning through modeling, field, and lab studies.

Research Interests

Dr. Wiles’ primary research interests are in glacial geology, climate change and tree-ring analysis. Recent projects have been funded by that National Science Foundation, the National Geographic Society, and the Keck Geology Consortium.
