I asked him where he got his inspiration from and how attached he was to Lyra, the main character in his Dark Materials Trilogy.
He gave me lots of answers - he told me that in Lyra's world there are daemons in the form of animals who are like ourselves.
He said he thinks we have daemons like that but in a different form.
He also told me his new book, Lyra's Oxford, was full of illustrations so it's quite different to the Trilogy.
I asked Philip Pullman what he was writing at the moment and said it was a continuation of the Dark Materials, hopefully out in two years time.
After the interview we went to his old college at Oxford University.
He pointed out where he used to climb onto the roof, and where he got the idea of Lyra climbing on roofs.
It was a really exciting day. Meeting my favourite author Philip Pullman was the experience of a lifetime."
