Welcome to my Research
I combine field work with a range of laboratory methods to address 'big picture' geological problems. My greatest passion is relating magmatism to tectonics. However, I study any kind of rock, mineral or structure that holds answers to important geological questions.
I am presently consumed by two separate programs of research: 1) the geological evolution of northern Yukon, and 2) the consequences of ridge subduction and slab window formation.
I collaborate with a range of specialists including Dan Marshall (geochemistry) and Dan Gibson (structure), who also belong to the P-T Research Group at SFU. For information on my output and impact, see my publications page.

I became hooked on Yukon geology from mapping 1:50k sheets for the Yukon Government in the early 1990's.
I carry out research on the petrology and tectonics of slab windows, worldwide.
