Trevor Porter

I am a professor in the Department of Geography, Geomatics and Environment at the University of Toronto Mississauga. My research focuses on northern paleoenvironmental change over recent centuries to millions of years BP. I specialise in reconstructing the past using natural indicators such as tree rings, leaf waxes, ice-rich permafrost, and the stable isotopes they contain. Most of this work is based in areas of N.W. Canada and Alaska.
