Alejandro Ciordia is a postdoctoral researcher at the Faculty of Political and Social Sciences at the Scuola Normale Superiore in Florence. He is part of the Centre on Social Movement Studies (COSMOS) and is currently working within the European Commission’s Horizon project DEMETRA (“Democratic Governance, Environmental and Climate Challenges, and Societal Transformation: Deliberation, Inclusiveness, and Citizen Empowerment for Sustainable Food Systems”).

His primary research interests lie in political sociology, with a focus on topics such as political polarization, collective action, protest, social movements, and socioecological transition. Methodologically, he specializes in social network analysis and mixed-methods approaches, combining statistical analyses of network patterns with qualitative evidence gathered through interviews and text analyses.

Alejandro earned his PhD in Sociology and Social Research from the University of Trento in 2020, conducting for his dissertation a network-analytic study on the changing patterns of inter-organizational collaboration within the Basque environmental field in the aftermath of violent conflict. From 2021 to 2024, he held a postdoctoral position at the Department of Social and Cultural Anthropology at the Autonomous University of Barcelona (UAB), where he remains an affiliated fellow of the COALESCE Lab (“Laboratory for the Computational Analysis of Egonetworks, Social Cohesion, and Exclusion”). Additionally, he has participated as a research assistant in international research projects at the University of Geneva and the King Juan Carlos University (URJC) and has been a visiting researcher at the University of the Basque Country (UPV/EHU) and Utrecht University.
