Troy is a geographer researching desert environments and societies. His current focus is on how climate hazards impact landscapes and people across Asian drylands. Troy's DPhil (Oxford) on the changing pastoral environment in Mongolia formed the basis for pioneering research in the Gobi desert. Work investigates how climate, drought, extreme cold and environmental transition affect the physical landscape, human well-being and state policy in Mongolia and China. He is now integrating South Asian and Middle Eastern arid zones with the Gobi to develop a continent-wide perspective on climate, environmental and social change in Asian desert and dryland regions.
Troy received the 2014 Margaret Mead Social Science Award from the British Science Association for work on climate hazards. Honours include the British Academy Post Doctoral Fellowship, the European Union's Science and Technology Research Mission grant for Arid Land Rehabilitation, the Royal Geographical Society's Thesiger-Oman Desert Fellowship, the UK-China Visiting Scholar exchange and the US State Department's Fulbright Scholar award. He serves as Vice-President of the Commission on Nomadic Peoples.
