Stephanie Stack is a marine scientist specialising in the ecology, behaviour, and conservation of marine mammals. For over a decade, she has led international research that informs conservation policy, contributing to whale-watching guidelines in multiple countries and landmark discoveries such as the world’s first documentation of humpback whale mating. Her doctoral research investigates how environmental change in Antarctic feeding grounds influences humpback whale migration, reproduction, and population health.

Alongside her research, Stephanie is committed to public education and marine conservation. She frequently works with environmental organisations and governments to promote sustainable ocean use, serves as a member of the International Whaling Commission’s Scientific Committee, and advises on conservation issues as a recognised subject matter expert. Building on her international experience, she is now applying her expertise to support research, conservation, and community engagement in the waters of eastern Canada. Her work is widely cited in the marine mammal science community and featured in global media, inspiring peers and the next generation of marine scientists.
