Rupert Crilly is a senior researcher on the Natural Economies team at the new economics foundation. Before that he was a scientific researcher: in Brunei he worked on orang-utan conservation, assessing the rainforest for their potential rehabilitation; in Canada he researched bone metabolism, then moved to France to study the evolution of bone mineralization. He has published in the peer-reviewed journal PLoS (Public Library of Science) on Natural Killer cells, focusing on the immune cell synapse. This work aimed to show how signals from cells such as cancers and virus-infected cells can elicit an immune response. Rupert received a degree in biology from Imperial College London and subsequently has moved into economics, studying at London School of Economics in 2008 and completing an MSc at University College London in 2009. His main research areas are the impact of growth on the environment, valuing the environment, and how policy can be made to increase sustainability.
