I am a postdoctoral fellow in the Department of Natural Resource Sciences at McGill University in Montreal, Canada. I am very passionate about science outreach and am currently partnered with Earth Rangers in their Northern Project to teach kids about the conservation of Arctic wildlife.
In addition to my work with Earth Rangers, I am doing research supported by the W. Garfield Weston Foundation and Fonds de Recherche du Quebec. I started working in the Arctic as a Master’s student studying high Arctic food webs, and have since worked in many remote areas across the Canadian Arctic; from Devon Island, Nunavut, to Kendall Island, Northwest Territories.
I currently study the effects of climate change on thick-billed murres, an Arctic seabird with a colony of 30,000 breeding pairs at Coat Island in Northern Hudson Bay, Nunavut. I am interested in the physiological response of murres to Arctic climate change, specifically the effects of changes in prey availability on their energetics and warming temperatures on their performance.
I completed my PhD at the University of Manitoba on beluga whales as sentinel species of environmental change in the Beaufort Sea ecosystem in partnership with communities in the Inuvialuit Settlement Region, Northwest Territories. In 2014, I was a Weston scientist on the Victoria Strait expedition in search of the lost Franklin ships, the Erebus and Terror. I was a Fellow for the Marine Working Group of the International Arctic Science Committee, and am currently a Fellow of the Royal Canadian Geographical Society.
