Her research applies low-temperature thermochronologic methods (fission-track and (U-Th)/He analyses) to geologic problems involving tectonics, structure, and geomorphology. Ann has worked on projects in Alaska (the Brooks Range), the Himalayas (Nepal, Bhutan, and Tibet), the Andes (Bolivia and Argentina), California (San Gabriel and San Bernardino mountains and the SAFOD project), and Spitsbergen. She is now working with Audrey Huerta of Central Washington University on a project on the formation of the Transantarctic Mountains.

Teaching

I normally teach Physical Geology (Geo105), Introduction to Field Methods (225), and Geomorphology (342). I occasionally teach Structural Geology and Advanced Field (325), and Sedimentology. 

 

Research

I am interested in studying a variety of geological problems involving tectonics, neotectonics, structure, and geomorphology.  I use fission-track thermochronology in my studies.  I have had several students do research projects with me using fission track analyses to study tectonic problems.  My current research focus is on the evolution of the Transantarctic Mountains in Antarctica; this project is funded by NSF (my co-PI is Audrey Huerta of Central Washington University).
