Research, innovation, science and technology are the very cornerstones of Cambridge. A city with 92 nobel prizes to its name - the work carried out here is world renowned.
Much of that work relies on foreign funding, whilst many of the students and the scientists here come from abroad.
At the Cambridge headquarters of Astex Pharmaceuticals, 20% of the workforce are recruited from the EU.
Their Chief Executive told ITV News Anglia that the free movement of scientists in and out of the UK is crucial to their success.
But not all scientists think Britain leaving the EU would be a bad idea.
Leave campaigners say a vote to get out have little impact on science and research, pointing to other non EU countries such as Switzerland and Canada which enjoy good access to EU research schemes.
According to the Royal Society, the UK paid £4.2bn to the EU research budget between 2007 and 2013 but won back nearly £7bn over that same period. And while EU funding was only 3% of the UK's total research spend in that time, it is vital money for universities, where it represented around 11% of their total research income.
Analysis from Universities UK shows that in the East of England, EU students generate £247.5m for the regional economy and support 2,295 jobs.
The University of Cambridge estimates that around 20 per cent of grants for research in the city come from Europe, while around 100 organisations from in and around the county are registered to take part in EU research.
Like most academic institutions, the University of Cambridge has come out in support of the remain campaign.
It's a decision that has caused some controversy among academics.
