London's economy is dominated by medical research, financial services, manufacturing,[1] and information technology.[citation needed] Much of the life sciences and biotechnology related research is conducted or supported by the University of Western Ontario (partly through the Robarts Research Institute), which adds about C$1.5 billion to the London economy annually.[2] Private companies in the industry like Alimentiv, PolyAnalytik, KGK Sciences and Sernova are also based in London. The largest employer in London is the London Health Sciences Centre, which employs 10,555 people.[3]
