Jarvis studied graphic design and previously worked as both a record sleeve designer and an animation director before becoming a children's book illustrator. Alan's Big, Scary Teeth is his debut title with Walker. About his picture book inspiration, Jarvis says, "The way I work is always visual. I will have an image or character in mind and I pull a story out of it. I doodle and doodle and doodle until I get it right." Jarvis lives in Manchester with his girlfriend and their cat.
