Before Kris Iyer was an actor, he was an engineer with a degree from the University of California at Berkeley. However, long before even that, he dreamed of being a musician. At age six, Iyer was given a toy organ for Christmas, and he had a guitar by age eight, with more equipment coming as he developed his hobby through adolescence. Even after he'd completed his college education, Iyer was still hoping for a musical career, though an amateur night appearance on the long-running program "Showtime At The Apollo" ended with him getting heckled off the stage. Unhappy with his engineering career, Iyer began taking acting classes and to his surprise started receiving work. Like many an Indian-American actor, the bulk of his television guest parts had him playing doctors in a variety of circumstances. Two of his more memorable turns were as Charlie Sheen's wisecracking M.D. on the sitcom "Two And A Half Men" and playing a physician of the future on the science-fiction program "Star Trek: Enterprise". Aside from his numerous parts as a medical practitioner, Iyer's most prominent television appearances include a two-episode stint as a terrorist on the action-suspense show "24". Iyer also had a noteworthy role as a vampire tracker on the popular supernatural drama "Buffy The Vampire Slayer".
