Acadia ALERT - Full Campus Closure Due to Weather

Today, February 16, 2024 at 2pm, Acadia University will close the entire campus, with the exception of residences and Wheelock Dining Hall, due to the forecasted weather. Wheelock Dining Hall may adjust their hours due to the weather and any change in hours will be communicated through Residence Life. The Acadia Athletic Complex, Vaughan Memorial Library, KC Irving Environmental Science Centre and the Manning Memorial Chapel will be closed in addition to the rest of the campus. Any events scheduled for today will be postponed or canceled.

The campus will remain closed until 12pm on Monday February 17, 2025. An update on campus conditions will be provided no later that 11am on Monday. Should conditions allow campus will reopen at 12pm.

Updates will be posted on www.acadiau.ca and pre-recorded on Acadia’s Information Line: 902-585-4636 (585-INFO) and on 585 phone system voicemail. If you need emergency-related information, please contact the Department of Safety and Security by dialing 88 on all 585-phone systems, or by calling 902-585-1103.

Research

My main research interests are metamorphic and structural geology and the tectonic evolution of orogenic belts with a focus on the interactions between accreted terranes and continental margins during collisional orogenesis. All my work follows a multi-disciplinary approach to the study of tectonic processes based on extensive field work augmented by laboratory techniques. While my work is broadly focussed on tectonic problems, the methods I use are heavily dependent on metamorphic petrology, structural geology, and geochronology as analytical tools that are critical in answering orogen-scale questions.

I have research projects in Cape Breton, mainland Nova Scotia, Newfoundland and Labrador, and Nunavik and Nunatsiavut. My major area of focus is the northern Appalachian system, but I also work in the Proterozoic New Quebec Orogen, and the adjacent Archean Core Zone. Many of my projects have a strong field geology aspect, and others are more laboratory based. The majority of the projects I have available have strong metamorphic and structural geology components, often coupled with geochronology, but I am always open to projects in related areas of geology depending on student interest. Projects are often built around skills that students wish to develop, or around tectonic questions that spark interest, so there are many different options for student work in my research program. Please get in touch about possible projects any time!
