All courses for every first-year Science student will be delivered online this fall. A limited number of students in their second, third and fourth years will return to campus for part of the semester.

The School of Geography & Earth Sciences will be renamed the School of Earth, Environment & Society effective July 6th, 2020.

My research primarily focuses on the structural, tectonic and magmatic evolution of continental margins, including the adjacent onshore areas and offshore sedimentary basins. I am particularly interested in rifting and breakup, rift-related magmatism, structural inheritance and mantle dynamics.

Geographically, my work to date has focused on the continental margins of the North Atlantic and surrounding regions including: Newfoundland, Greenland, Jan Mayen, Labrador and the UK/Irish margin. The nature of my work requires a multifaceted approach incorporating a wide variety of approaches and methodologies such as: seismic interpretation, field-based studies, numerical modelling, petrology, structural modelling and geochemistry
