Earth and Environmental Sciences (SEES)

Profile

General Information

My current research focuses on the chemistry of accessory minerals in granitoids from different orogens to trace chemical systematics and use them to understand their petrogenesis, and in turn as tracers of tectonic environment of ancient granitoids (in collaboration with Craig Storey and Mike Fowler). As a metamorphic petrologist, I am also interested in the study of high grade rocks (migmatites, blueschists and eclogites).

Teaching

I assist with the 1st year metamorphic petrology practicals.

Career
