About me

I'm a marine biologist whose research has explored life in the deep ocean that covers most of the world. As a "bathynaut", I went on the first submersible dive to the world's deepest hydrothermal vents (hot springs 5 km / 3.1 miles down on the ocean floor) and the first submersible dives to reach 1 km (0.62 miles) deep in the Antarctic.


These days I'm a university educator, training the next generation to explore this deep-ocean planet. I'm also a popular-science author & former science journalist, a science communicator advising oceanic documentaries & sci-fi series, and co-founder of a company that trains scientists in communication skills to share their work more widely.
