Jules is a prominent Australian book illustrator, but this is his first adventure with Dr. Karl. His passion for science illustration stems from the late 90s when, while studying animation, Jules was leafing through one of Karl's earlier books. Thinking aloud that he could illustrate like the ones inside, and having never considered illustrating books before, this planted a seed. Years later, when asked to illustrate the first of the WeirDo series with Anh Do, Jules recalled that moment. Thus began a bucket-list ambition - to draw for Dr. Karl. The rest, as they say, is scientifically-accurate history.
