I’m Dr Tim Gregory, a nuclear scientist working in a lab at Sellafield.

I’m also a speaker, popular science author, regular on radio, and occasional television presenter.

 
 
 
“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.”
— Col Chris Hadfield, Former Astronaut and Commander of the International Space Station
