Dr. Campbell's research focuses on policies and projects designed to reconcile wildlife (and other resource) conservation with socio-economic development, primarily in rural areas of developing countries. She studies the process of policy making, the transition from policy to practice, and the impacts of (and responses to) implementation at the local level. At the policy making stage, she examines how the interaction of science and other values, and how negotiations between stakeholders (local people, bilateral agencies, NGOs, and 'experts') inform the process. Specific policies include participatory development, community based conservation, sustainable use, and ecotourism. A major research focus has been on marine turtle conservation policy, and its implementation in Latin America and the Caribbean. Dr. Campbell is more generally interested in research methodology, including qualitative methods, inter-disciplinary research, and ethics.
