Lisa Pettibone is a political scientist looking at the role of discourse and citizen engagement in sustainability. Her first book, Governing Urban Sustainability: Comparing Cities in the USA and Germany highlighted the role of “sustainability-minded groups” in pushing local discourse related to sustainability. She also edited a symposium in the Journal of Environmental Studies and Sciences on integrated approaches to sustainable cities, appearing in March 2017. Seeking to link sustainability to participatory research approaches, she coordinated the citizen science capacity-building project funded by the German Federal Ministry of Education and Research from 2014 to 2016. This led to publications on citizen science and participation, lifelong learning, and sustainability, as well as a guide for citizen science practice coordinated with 32 coauthors. At the Rachel Carson Center, she is examining the role of ideational change in sustainability transitions. Lisa holds a BFA from New York University, an MPA from George Washington University, and a PhD from the Freie Universität Berlin’s Environmental Policy Research Centre (FFU). She has worked in the US Senate and Department of Energy, the German Bundestag, and the Museum für Naturkunde Berlin.
