Dr. Ravi Chakrabarti is a main character of iZombie. Ravi is a Medical Examiner with the King County Medical Examiner's Office. He also becomes Liv's friend, partner, and confidante, and their relationship is a mutually-beneficial, yet unlikely, friendship that proves to be as solid as they come.
In Pilot, Ravi confirms his suspicions that Liv is indeed a zombie. After he asks her to sew a victim back together, he leaves her alone only to return not long after catching her eating the victim's brains. He becomes excited about her condition and begins pressing her with questions after he explains how he suspected she was in fact a zombie. While they're talking detective Clive Babineaux walks in on them to ask Ravi if he has any information on the Jane Doe. When Liv has a vision about the Jane Doe and tells Clive about it and he asks how she would know that, Ravi covers for her by telling him that Liv's a psychic. After running more tests on Liv he begins the process of searching for a cure while continuing to help her and Clive.
In Brother, Can You Spare a Brain?, Ravi and Liv go to a crime scene to help the investigation of a murdered artist. He also enlists a police sketch artist to draw the face of the zombie Liv saw in her vision so that they can find him. When it works and Blaine shows up at the morgue Ravi begins to run tests on him, questioning him as well. He later attends a party with Liv and Det. Babineaux to work on the investigation further.
Ravi Chakrabarti is a high-energy, enthusiastic nerd with a brilliant mind; however, that mind does not seem to be equipped with a filter or an off switch. He is hard-working, smart, and a kind and caring friend. He is good friends with Liv and has a knack for observation as he successfully deduced Liv is a zombie. He even goes so far as trying to develop a cure for Liv.
Ravi was fired from the Center for Disease Control and Prevention over his obsession with prevention of a biological weapons attack and the prediction of a zombie outbreak which later turned out to be correct.
Ravi is a tall, thin man of South Asian descent with brown eyes, black hair, and a beard. Once Ravi’s infection grows he begins to develop a small white streak in his hair. In 2030, his hair has begun greying.
