William Warr


Honorary Senior Fellow

William completed his DPhil at Oxford, focussing on obesity. He previously completed an MPhil in Public Policy from Cambridge. He also has deep health policy experience in Government, as the former senior health policy adviser to the Prime Minister, a position he held during the Covid-19 pandemic, where he was closely associated with many aspects of the response, including helping broker the Oxford-AstraZeneca vaccine partnership, setting up the testing programme and the vaccine roll-out. He also led the Prime Minister's obesity policies, including restriction junk food promotions in supermarkets, adding calorie labels to menus and designing laws to restrict junk food adverts. 

Prior to this role, William worked for Prof Sir John Bell, writing the 2017 Life Sciences Industrial Strategy. This included designing programmes, such as "Our Future Health", which aims to be one of the largest cohort studies in the world, recruiting 5m people to try to spot, prevent and treat diseases earlier.

In his free time, William was a keen rower, rowing for both Oxford and Cambridge in the boat race, winning for Oxford in 2017, and is a team GB Gold Medalist.
