Who: Graham Pearson
Experience: He has been chased by polar bears in the Northwest Territories, ostriches in South Africa and a nine-foot-long cobra in Namibia — all while in pursuit of diamonds. As the Canada Excellence Research Chair in Arctic Resources at the University of Alberta, he routinely travels the world gathering samples from deep inside the earth’s crust that tell him how diamonds form, where they come from and how old they are.
