Hello, I’m Tim Gregory.

I’m a geologist who studies rocks from outer space, and I'm working towards a PhD in Cosmochemistry at the University of Bristol.


Tim Gregory gets it. Drawing on his deep technical education and boundless curiosity, he brings a childlike wonder of discovery to everything he sees. He shows an uncanny ability to swiftly understand, to clearly explain, and to be joyful in the process. His scientific delight is contagious.
