Christopher McCulloch, also known by the pseudonym Jackson Publick, is an American storyboard artist, writer, director, producer, and voice actor.

Before he became a student at Rutgers University, Christopher McCulloch worked in his hometown comic-book shop and wrote comics stories in his spare time.

His employer published his superhero spoof Cement Shooz, and when McCulloch promoted it at a comic book convention in New York, he was approached by Ben Edlund, creator of the comic-book character the Tick, who had read Cement Shooz and offered McCulloch the chance to write for a spinoff of The Tick.

When the Fox Kids Network increased its order of Edlund's animated series The Tick, McCulloch was drafted as a staff writer and a storyboard artist.

When The Tick was canceled, he moved back to New York City and pitched a revised version of The Venture Bros. to Comedy Central again.
