Paul Ryan studied at the Massachusetts College of Art, and began his career in comics the mid-1970s, while still maintaining his dayjob as a graphic designer for an engineering firm. His earliest comic efforts were doing backgrounds for Bob Layton. Shortly afterwards, Ryan got assignments from Marvel, doing inking on 'The Thing' and pencils on 'Squadron Supreme', a 'Thor' graphic novel, 'DP7', ' Quasar', 'The Avengers', 'The Avengers West Coast', 'Iron Man', 'Fantastic Four' and 'Ravage 2099'. Ryan was the penciller and co-plotter for 'The Fantastic Four' for nearly five years, being behind only Jack Kirby and John Byrne as the artist with the longest run on the comic. He additionally co-created 'Breed' for AC Comics in 1984, and worked on 'Phantom' stories for the Scandinavian magazine.
In 1996, he switched to DC, where his credits include 'Superman', 'Man of Tomorrow', 'Flash', 'Legion Science Police', 'Legends of the DCU: Crisis on Infinite Earths', 'Batman: No Man's Land', 'Shadow of the Bat', 'Aquaman', 'Gotham City Secret Files', 'Superboy' and 'Green Lantern'.
