Asha de Vos’ journey from deck hand to marine science leader

Science Friday | Jul 24

The tropical waters of Sri Lanka, an island off the coast of India, are home to a population of blue whales unlike any other. These whales stay put, while every other known population migrates. That discovery was made by budding scientist Asha de Vos more than 20 years ago—it made a splash, and so did she. She later became the first Sri Lankan to earn a PhD studying marine mammals, charting a new scientific path in her country.

De Vos joined Host Flora Lichtman in 2025 to discuss her path into science, what it means to be the first in her field, and how she built a marine biology program from the ground up.

Guest:

Dr. Asha de Vos is a marine biologist and the founder and executive director of the non-profit Oceanswell. She’s based in Sri Lanka.
