Fields of Study:

Mineralogy, igneous and metamorphic petrology, and Tectonics

Research Interests:

My research is solving the history of mountain belts (such as the Coast Orogen of British Columbia and southeastern Alaska or the older Appalachians in Pennsylvania) by looking at as many different aspects as possible of the kinds of rocks, the time the rocks formed, the location in which they formed, the way the earth moved. The total time span for the mountain belt I study in British Columbia is from 110 million years ago to the present.
