His research focuses on the rates, causes, and consequences of Arctic environmental change. He and his students work collaboratively with indigenous hunters and trappers to gain insight into regional environmental change and to guide detailed field research investigating the processes facilitating change. To place their field studies in a regional context, and to examine variation at a broader scale, they use remote sensing and modelling. Trevor’s recent research has focused primarily on: 1) vegetation change, 2) thawing permafrost, and 3) Arctic storm surges.
