In the fall of 2005, Joy joined the CBS television show, CSI: NY, during its second season as a recurring character, Dr. Sid Hammerback, the Chief Medical Examiner, and became a main cast member in season five. Joy stated, "I basically read the script and then look up everything on Wikipedia that I don't know, and try to find out how to pronounce all the long words and get my head around actually what it is that I'm conveying, because often my character has a lot of explaining to do."
