The University of Groningen is offering a PhD position in Environmental Psychology focused on motivating people to contribute to societal transitions. This opportunity is part of the national NWO-NWA ECCO project, which aims to empower citizen collectives in driving just and sustainable transitions. The research will investigate how citizen collectives influence motivations, shared identities, and behaviors among both participants and non-participants, examining the potential for polarization or inclusive engagement. As a PhD candidate, you will develop your own research questions, collect data, and share findings with both scientific colleagues and professional partners. The project involves a longitudinal field experiment with over 40 communities, using surveys and experimental methods to assess changes in motivation and identity. You will also develop the 'Motivation Mapper' tool to help citizen collectives track their impact. Supervision will be provided by Associate Professor Lise Jans and Professor Ellen van der Werff, alongside a multidisciplinary team within the ECCO consortium. The Environmental Psychology Research Group at the University of Groningen is internationally recognized for its work on sustainable behavior, climate adaptation, and behavioral change interventions. The group collaborates with various academic, governmental, and NGO partners. Applicants should hold a Research Master or Master’s degree in social or environmental psychology or a related field, with strong quantitative and experimental research skills. Proficiency in English is required, and Dutch is preferred. Candidates should be enthusiastic about academic writing, collaboration, and translating scientific insights into practical guidelines. Organizational skills, perseverance, and conceptual ability are essential. The position offers a competitive salary (€3,059–€3,881 gross per month), generous vacation and holiday allowances, and opportunities for professional development. The contract is for four years, with an initial 12-month appointment and extension upon positive evaluation. The application deadline is 15 February 2025, and the starting date is 1 September 2026. To apply, submit your CV, motivation letter, academic transcripts, proof of English proficiency, and other relevant documents via the university’s online portal.
