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.
