Tulsi, who hails from Patna, completed his schooling at the age of nine and had a Bachelor of Science (BSc) degree by the time he turned 10.
He further went on to get a Masters in Science (MSc) at the age of 12, receiving a doctorate from the Indian Institute of Science at 21.
"I am delighted because IIT Bombay is a very reputed institute, not only in India but the world over. I was offered to teach as an Assistant Professor and I am proud that at the age of 22 I am the youngest professor in India," said Tulsi.
Tulsi chose the IIT over job offers from Waterloo University in Canada, and the Indian Institute of Science Education & Research (IISER) in Bhopal.
"He has job offers from Canada and Bhopal. But due to the patent problem in Canada, it will be a national loss. And because the institute in Bhopal is new, I suppose the laboratories might not be that good. Therefore we have given preference to IIT Mumbai," said Tulsi Narayan Prasad, father of Tathagat.
