About me

I’m a writer, marine biologist and broadcaster.

When I’m not on or under the waves, I write and talk about the oceans, the things that live there and the connections between people, science and the living world.

My books include the Guardian bestseller Spirals in Time, and New Scientist book of the year Eye of the Shoal.

I appear on various BBC radio programmes and present the Earth Unscrewed podcast.

I also teach marine biology and science writing at Cambridge University and I’m scientific advisor for the marine conservation charity Sea Changers.

Here are some of my radio highlights.
