David Williams is a conservation scientist interested in finding ways to balance the demands of food production and biodiversity conservation. After a fieldwork-heavy PhD at the University of Cambridge in the UK, supervised by Prof. Andrew Balmford, he is now working with Prof. David Tilman at UCSB using large datasets to explore the ultimate drivers of biodiversity loss, and how we can work to reduce them. He is also interested in working to make conservation more evidence-based, having worked with Prof. Bill Sutherland on the project ConservationEvidence.
