Callum Roberts is professor of marine conservation at the University of York. His research focuses on threats to marine ecosystems and species, and on finding the means to protect them. His main research interests include documenting the impacts of fishing on marine life, both historic and modern, and exploring the effectiveness of marine protected areas for conservation and fisheries management purposes. For the last 25 years he has used his science background to make the case for stronger protection for marine life at both national and international levels. His award winning book, The Unnatural History of the Sea, charts the effects of 1000 years of exploitation on ocean life. Callum’s second book, Ocean of life: how our seas are changing, shows that the oceans are changing faster and in more ways than at any time in human history. His research team provided the scientific underpinning for half a million square kilometres of marine protection in the North Atlantic that was established at the OSPAR ministerial meeting in September 2010.

Callum is currently working with the UN Ocean Sanctuary Alliance and 10 x 20 initiative to encourage nations to meet their commitments to establish at least 10% of their seas as marine protected areas by 2020. He is on the Board of Blue Marine Foundation and is science advisor for the BBC’s forthcoming flagship series Blue Planet II. He has been a Pew Fellow in Marine Conservation since 2000.
