Dr Tim Gregory is a planetary geologist. His cosmochemistry research focuses on the geology of the early Solar System. After completing his PhD at the University of Bristol in 2019, he took up a research scientist post at the British Geological Survey in Nottingham.

Cosmochemistry combines two of his great loves in life: rocks and space. He researches the timing of events during the formation of our Solar System over 4.5 billion years ago by studying the oldest rocks we know of — meteorites.

Tim surpassed thousands of applicants for a place in the six-part BBC2 series Astronauts: Do You Have What It Takes?, where he was put through the full rigours of astronaut selection and reached the final three.

Since then, he has gone on to present a segment about meteorites on BBC4’s The Sky at Night and has made live television appearances on BBC Breakfast, BBC Look North, and BBC Points West. He has a monthly spot on BBC Radio Bristol to talk about space exploration and regularly features on local and national radio to talk about events in the world of space science.

Tim loves nothing more than sharing his love of science and the wonders of the natural world. He regularly speaks to audiences of all sizes and ages on topics such as cosmochemistry, planetary science, and the importance of science in society. His enthusiasm is infectious and his deep knowledge of planetary science shines through.

Originally from West Yorkshire (and with the accent to prove it), Tim completed his undergraduate degree at the University of Manchester where he achieved a first class with honours in Geology with Planetary Science (MEarthSci). He discovered his love for cosmochemistry during a ten-week internship at NASA’s Johnson Space Center in Houston, where he investigated the history of water-rich asteroids.

In 2020, Tim’s first book, Meteorite: The Stones from Outer Space that Made our World was published by John Murray Press.

Praise for Meteorite:

A captivating blend of painstaking detective work and dramatic cosmic events. The impact that rocks from space have had on our culture, and on our knowledge of where we come from may surprise you.

— Jon Butterworth, Professor of Physics at UCL and author of Smashing Physics

Tim Gregory gets it… he brings a childlike wonder of discovery to everything he sees… His scientific delight is contagious.

— Chris Hadfield, Astronaut

Blue Sky Science – Lessons for Innovation

So-called ‘blue sky science’ — that is, science that is curiosity-driven with no explicit or immediate real world application — is part of the lifeblood of the scientific enterprise and technological innovation. Unconstrained by specificity, it often takes us to uncharted territories, and from it come many unexpected and miraculous discoveries. Indeed, many of the things we take for granted in our everyday lives saw their inception in esoteric and abstract questions of academic research – and there are many lessons here for innovation in business too.

Cosmochemistry – Lessons from the Bigger Picture

The charred remains of stones that fall from the sky have captured the human imagination for millennia, and using the tools of modern science we have read from them the most ancient tales in the Solar System: the coming together of our planetary system, the formation of worlds, and clues to our own origins. Meteorites are custodians of deep time and interstellar chemistry. These rocks from outer space can offer lessons about ourselves and our organisation by taking a step back and looking at the bigger picture.
