He attended the boarding school Vikas Vidyalaya, Ranchi until 1982. After graduating from Allahabad University, he moved to the United States for higher studies.[2] Perhaps chief among his mentors in his BFA program Stony Brook University was Farley Richmond, who also urged him to return to India and Hindi theater and film in 1995.[3]
