Tanya O'Garra received her Ph.D. from Imperial College London in Environmental Economics. She has carried out economic valuation studies of hydrogen transport technologies in the UK, traditional fishing grounds in Fiji and worldwide climate change adaptation projects. Tanya will be working with Professor Dave Krantz, at the Center for Research on Environmental Decisions. Most present-day, environmental problems result from many individual actions. Though these may not be harmful by themselves, together they can combine to produce major environmental impacts. She will be using experimental, economic approaches to identify factors that might best enhance cooperation and other-regarding behavior among large numbers of anonymous agents. She will explore whether moral and personal norms might effectively stimulate cooperation in these large-scale social dilemmas, particularly in conjunction with other stimuli such as subsidies and leadership. Tanya will also be working on the Columbia University-led Polar Learning and Responding project (PoLAR) researching the impact of novel educational approaches on adult learning about climate change and the poles.
