M. (Marc Esteve del Valle) Esteve Del Valle, PhD
Field/Discipline
Expertise
Marc Esteve del Valle is a Senior Lecturer with Ius Promovendi at the Research Centre for Media and Journalism Studies. His research and teaching focus on the intersection of digital media, environmental sustainability, and social change, with a particular emphasis on mediated climate change communication.
Marc’s work centers on studying how the climate crisis is (re)presented, discussed, and debated across social media platforms. He is especially interested in the networked publics that form around climate issues: how individuals, activists, and institutions navigate visibility, authority, and emotion in algorithmic environments. He studies communication phenomena such as online environmental polarization, climate misinformation, eco-anxiety, and communication about AI's environmental footprint.
Marc’s broader research also examines how platforms shape public discourse and participation, whether through the dynamics of political debate, the educational uses of digital platforms, or the political economy of streaming services. Across all of this work, Marc is driven by questions such as: Whose voices are being amplified? How are digital platforms shaping collective understanding? What new forms of power and exclusion are emerging online?
Marc has published over 40 peer-reviewed articles in leading media and communication journals. He is the author of a book on the liberalisation of the Mexican telecommunications market (in French, 2012). He is also the editor of a forthcoming volume, Rural Media Studies: Global Perspectives (2026), and has guest-edited two special issues: one on Homophily in Social Networks and a more recent one on Digital Resilience within a Hypermediated Polycrisis. Marc's work has been supported by multiple research grants and awards from public institutions and funding agencies in Spain, Canada, and the Netherlands.
