Harrison received a B.F.A. from Washington University in St. Louis, and then attended the program in Painting and Printmaking at Yale University. After earning an M.F.A. in 1999, he moved to New York City where he maintained a studio practice, taught, and worked in galleries and auction houses. During this time, he showed his work in several exhibitions in New York and Dallas, TX. In 2008, he moved to Austin to attend the M. Arch I program at the University of Texas School of Architecture. Before moving, Harrison worked at Tod Williams + Billie Tsien in New York City, and during school he took time off to do an internship at Jean Nouvel Design in Paris. In Austin, Harrison has worked at Furman + Keil, Dick Clark + Associates, and Faye and Walker. In addition to his work with Murray Legge, Harrison continues to paint, and he keeps a studio near his home in northeast Austin. When not busy with art and architecture, he and his lovely wife Diana are usually having fun with their two young and highly energetic boys.
