In 2003, Glenn received his Masters in Science Communication from London's Imperial College of Science, Technology and Medicine. He wrote his first popular science book in 2006, whilst working at the Science Museum, London. There, he managed the Interactive Galleries'
Explainer Unit, and also wrote and edited science shows for live stage performances and for a monthly show on BBC radio.

He wrote his first book, he says, "to give kids interested in science what they really wanted: answers to the questions that they (rather than I) wanted to talk about. I wanted to steer them from their own musings into those of science itself, and in so doing get across the rudiments of astronomy, anatomy, genetics, engineering, and more. But rather than simply provide the "answers", I wanted to show children that when it comes to science, it's not just about what we know – it's about how we know it. Above all, the process of science grows from a spirit of inquiry – one which most children innately possess, but not all are encouraged to foster."

"I believe that it's critically important for children to grow up with a true and passionate appreciation of what science is, and what it does for us and the world. I write my books to encourage children to take ownership of science, to inspire them to learn more, and – even if they don't actually become working scientists – to help them embrace science as a part of their education, knowledge and worldview."

In June 2007, he moved to the United States. He now lives and works in Raleigh, North Carolina, with his wife Heather and an increasingly large and ill-tempered cat.
