In a letter to 'The Times' newspaper, a total of 150 fellows of the UK's Royal Society signed up to voice their strong support for Britain staying within the EU in the lead up to an in-out referendum on June 23.
Shankar Balasubramanian from the field of chemistry, Harshad Badeshia representing metallurgy, Partha Dasgupta from economics and K J Patel from molecular biology are the Indian-origin names on the letter, which warns of "disaster for UK science" if Britain were to exit the 28-nation economic bloc or so-called Brexit.
"The Royal Society fellows have signed the letter in their personal capacity," a spokesperson said.
The letter backed by 'A Brief History of Time' author Hawking, reads, "The EU has boosted UK science in two crucial ways. First, increased funding has raised greatly the level of European science as a whole and of the UK in particular because we have a competitive edge."
"Investment in science is as important for the long-term prosperity and security of the UK as investment in infrastructure projects, farming or manufacturing; and the free movement of scientists is as important for science as free trade is for market economics," the letter adds.
