Greg Miller is an American animator, cartoonist, writer, storyboard artist, and composer. His art style is based on the animation style of Schoolhouse Rock!, which was used in his own television series, Whatever Happened to... Robot Jones?, airing on Cartoon Network from 2002 to 2003^[2] and his short film, The Wizzard of Krudd, a canceled Nickelodeon short featuring the voice of Devon Werkheiser as the protagonist.^[3] He worked on the production of Shrek the Third and Monsters vs. Aliens as the additional storyboard artist. His recent credits include being a storyboard artist, writer, animator, and character designer on Secret Mountain Fort Awesome, Gravity Falls, and Uncle Grandpa.

Miller grew up in Upper St. Clair, Pennsylvania near Pittsburgh. He graduated from Upper St. Clair High School in 1992 and went on to attend the University of the Arts in Philadelphia. While there, he earned an internship at Hanna-Barbera that would eventually lead him to drop out of college after receiving a job offer to work on Dexter's Laboratory.^[1]

Miller began his career at Hanna-Barbera as a writer and storyboard artist for Dexter's Laboratory which aired on Cartoon Network.^[1] He also later worked on Cow and Chicken^[2] and The Powerpuff Girls as a member of the production company. In between stints at Hanna-Barbera, he worked for Nickelodeon (on CatDog and The Angry Beavers) and at Disney (on Nightmare Ned).^[1]

While working at Hanna-Barbera, he pitched the company a new show called Whatever Happened to... Robot Jones?. Hanna-Barbera declined, prompting Miller to take the pitch directly to Cartoon Network. Cartoon Network purchased the pilot along with the pilots of 9 other shows with the intent of trying them all out over one summer. Cartoon Network executives chose 3 (including Robot Jones) to be voted on by viewers in August 2000^[1] in an event known as The Big Pick or Big Pick Weekend. Robot Jones received 23% of the vote, finishing second and losing out to The Grim Adventures of Billy & Mandy created by Maxwell Atoms.^[4]
