Sonya Lee is a Korean-Canadian producer-director and National Geographic Explorer focusing on stories that intersect science, nature, people and culture.  

Her current projects combine her love of food, Korean culture and ocean conservation with a documentary series called Our Ocean Table for TELUS Originals and a short documentary exploring the fishery behind a Korean traditional dish, produced with support from the National Geographic Society.

Her most recent film, Jawsome: Canada’s Great White Sharks, aired on CBC’s The Nature of Things and has been nominated for Best Science and Nature Documentary or Series for the 2025 Canadian Screen Awards. It is currently streaming internationally on National Geographic Disney+ and Hulu. 

With a background in marine biology and over a decade of experience in science communication, Sonya was previously a producer for the National Film Board of Canada’s Ocean School project, producing over 100 media pieces including documentaries, VR/AR experiences, and multimedia interactives. 

Dr. Heather Bowlby is a research scientist who has focused on conservation and fisheries biology for more than 20 years. Her research interests relate to how populations respond to threats, the factors that cause them to change in size, and how different types of data can be combined to generate new ecological knowledge. She has worked on numerous species in both marine and freshwater environments, primarily studying lobster, Atlantic salmon, gaspereau, and sharks.  Currently, she leads the Canadian Atlantic Shark Research Laboratory at Fisheries and Oceans, Canada, with on-going projects on blue, porbeagle, shortfin mako, basking and white sharks. She is also an adjunct professor at Dalhousie University, serves on the Marine Fishes species specialist subcommittee for the Committee on the Status of Endangered Wildlife in Canada (COSEWIC), and is the Canadian science delegate to the sharks working group at the International Commission for the Conservation of Atlantic Tunas (ICCAT).
