I am a geographer whose work examines the governance of contested environmental problems, particularly relating to bioenergy and climate change. I use qualitative research methods to analyse how different kinds of knowledge about environmental problems are produced, circulated and interpreted, and how knowledge intersects with wider governance objectives and value judgements in specific political contexts. My previous work has examined debates about EU biofuels policy, the ‘dieselgate’ controversy in Europe, public perceptions of climate geoengineering, and the work of chief scientific advisers in UK government.
