Grant has designed his research program to address Federal priorities to conserve Arctic marine birds and ecosystems. He leads multidisciplinary research with collaborators to provide insights into Arctic seabird ecology including foraging, reproduction, migration, winter distribution, and how seabirds are affected by changing climate and emerging diseases in the north. In addition, several projects focus on the harvest of some marine bird species by Inuit because of the importance of ensuring sustainable harvest levels, as well as incorporating Indigenous needs into conservation and management strategies in northern Canada and Greenland. Most studies are collaborative and multidisciplinary in nature linking academia, government, industry, northern communities, and indigenous organizations.  He takes a keen interest in the professional development of northerners (Inuit Field Training Program), and early career scientists through mentorship.
