Jim is the author of seven graphic novels about scientists (so far), on topics ranging from physicists to paleontogists to behaviorists. He's probably the only comics writer whose books have received acclaim from both Physics World and Vampirella Magazine.

Upcoming titles include biographies of Richard Feynman and the Trimates (Jane Goodall, Dian Fossey, and Biruté Galdikas) for First Second, and "T-Minus," the story of the space race, for Simon & Schuster’s young adult imprint Aladdin.

His day job used to be as a nuclear engineer. He's now a librarian at the University of Michigan.
