Gaia is an award-winning science journalist, author, broadcaster and speaker. She is particularly interested in how human systems and Earth's planetary systems interact, and has travelled the world extensively to research it.

She writes books and articles, including for the BBC, The Guardian, New Scientist, Australian Geographic, Science, makes and presents science documentaries for radio and television, and gives talks around the world.

Previously, she held senior editorial positions at the science journal Nature, Nature Climate Change, and New Scientist magazine. 
Gaia is also an Honorary Senior Research Fellow at UCL's Anthropocene Institute and a Fellow of the Royal Society of Arts.

This is a unique time in Earth's history, in which climate change, globalisation, communications technology and increasing human population are changing our world – and us – as never before.

She documenting these changes, talking to ordinary people, scientists and heads of state as we enter into the Anthropocene.

Travelling around the world for 800 days formed the basis of her book Adventures in the Anthropocene, which won the Royal Society Prize for Science Books (the first woman to do so).

Gaia has subsequently written two books, Transcendence and Nomad Century, exploring how a smart ape became a planet-dominating force, rewriting the story of our 'ascent', describing the co-evolution of our biology and environment.
