Changgeon works in cinematography and set lighting for film and television. He has freelanced as a motion graphic designer and animator at WWE, Madison Square Garden, and The Economist. He has taught undergraduates in motion graphics and animation as well as young people in the autism spectrum at a non-profit organization in Pittsburgh. While 2D and 3D creative technologies interest him, traditional drawing with pencil and paper takes up most of his time. You may find him drawing at a bar or park with his little sketchbook. If you see him, take out your pad and join in.
