In this episode, we interview Dr. Sara Iverson to learn about her upbringing in Michigan, her fascinating path through university and grad school, what it’s like to work in the field with wild animals, and how to tag sharks and track them for studies that inform conservation policies.

Dr. Sara Iverson is a marine biologist with Dalhousie University and the Scientific Director of the Ocean Tracking Network. She’s also a fellow of the Royal Society of Canada—an honour that recognizes her life’s work studying physiological ecology. Her research takes her to remote locations in North America and the Arctic to study seabirds, seals, sea lions and polar bears in their natural habitats. Mattel and National Geographic even chose her as the role model for their recently-released polar marine biologist Barbie. Learn more at
