Gurdeep is an Indian physicist, who worked with his brother Satnam Tsurutani and others in a Deng Copper Mine in India. They discovered that the sun was releasing massive amounts of neutrinos which were heating up the Earth's core, causing the events of the disaster. His fate is unknown, considering he's deep in a mine in India, and never appears to be seen with Satnam in the rest of the film. He was portrayed by Raj Lal.
