Once his three children were more able to look after themselves, Kevin Buzzard wanted to return to hard research mathematics.

“My name's Kevin Buzzard. I'm a number theorist working at Imperial College London. I spent some time at the beginning of this century bringing up three kids.”

“When that was sort of over and they were able to look after themselves a lot more, uh, I wanted to get back into doing hard research mathematics, and I realized that there was a huge amount of material that I was gonna have to sort of catch up on.”
