Professor Kelsey's research examines the role of interests in underpinning international environmental policy and negotiation. In particular, she focuses how changes to interests can occur over time, and how these changes shape policymaking. Her projects have looked at the role of feedback processes between policy and industry in explaining the differing outcomes of the international negotiations surrounding ozone and climate change, as well as the ongoing process of climate negotiations. Prior to joining the Elliott School, she was a postdoctoral scholar with the Center for Information Technology Research in the Interest of Society & the Berkeley Roundtable on the International Economy (Berkeley); and with Resources for the Future (DC).
