Research Interest

My research is focused is on understanding how Earth’s geography has changed over geological time, and determining the significance of Earth’s changing geography for the evolution of the biosphere and atmosphere. I study current and ancient mountain belts, as mountain systems develop along plate margins and provide a record the long-term movements and plate interactions of continents.   Outreach is central to my science, for a public ignorant of the basic workings of the Earth and of the depth of Earth history, will never be able to imagine or comprehend the substantial challenge that ongoing climate change presents for humanity.

Research Opportunities

Current research projects include:

1) Tectonics and Paleogeographic evolution of the Cordilleran Orogen of Western North America
2) Vancouver Island: Tectonic Processes within a long-lived convergent margin
3) Variscan Orogenesis: The construction of Pangea
4) Oroclines and their implications for Plate Tectonics

Interested students should send along a CV, and a short statement of their research interests.

Courses

EAS 333 - Advanced Geology Field School

Advanced field practice in geology. Details and areas of study may vary from year to year. Consult the department about current offerings and timing. Topics vary, and will include the study and mapping of deformed sedimentary, igneous, and metamorphic rocks, mineral deposits and their associated host rocks and alteration, and structures in the field. May be taken more than once for credit provided no topic is repeated. Co-prerequisites: EAS 233, 234 or 237, 331 and 332. Requires payment of additional student instructional support fees. Refer to the Tuition and Fees page in the University Regulations section of the Calendar. [Faculty of Science]
