London Mayor Boris Johnson says his city's life sciences sector is growing and encourages more members of the Boston area's highly trained workforce to consider launching or expanding their companies.
Johnson visited the Massachusetts Institute of Technology on Monday. He says his city's economy is undergoing its "greatest transformation" since the Industrial Revolution.
Johnson says the tech industry accounts for 27 percent of all new jobs in London, a larger share than the city's vaunted financial services sector.
The mayor is on a six-day trade mission to the United States. The trip includes stops in New York and Washington, D.C.
A massive snowstorm has scuttled some of Johnson's public appearances in the Boston area, including a forum about London's 2012 Summer Olympics experience. Boston is bidding for the 2024 Olympics.
