I am an assistant professor and the Chair of the Reasoning and Argumentation Lab (ArgLab) at the Nova Institute of Philosophy, Nova University of Lisbon, Portugal. I completed my PhD at the University of Amsterdam (2010), and from 2010 to 2016 worked as a post-doctoral fellow of the Portuguese Foundation for Science and Technology (FCT), before becoming an assistant professor in 2016. My work focuses on the basic issues in the philosophy of language and argumentation theory such as rationality of everyday conversations, practical reasoning, pragmatic meaning, social and strategic aspects of speech acts, fallacies. I teach Philosophy of Communication and Argumentation courses and supervise PhD students and post-doc researchers. I am currently leading the Horizon 2020 COST Action project CA17132, “European Network for Argumentation and Public Policy Analysis” (2018-2023), where philosophical and linguistic concepts and methods are applied to a critical study of public argument. From 2017 to 2019 I was a PI of “Ecological reasoning and decision making in innovation-oriented industry sectors at the periphery of Europe: Reconciling divergent values and interests”, an international project co-funded by the Portuguese (FCT) and Turkish (TÜBITAK) science foundations. These projects situate philosophical inquiry in the context of key societal challenges (climate change, health). My most recent publications include papers on “Illocutionary pluralism” (Synthese, 2021) and on “Conclusions of practical argument” (Organon F, 2021). I am under contract with the Cambridge University Press, finishing a monograph on “Argumentation in Complex Communication” (co-authored with Mark Aakhus, Rutgers University). My current research revolves around the issue of verbal and conceptual disagreements, and their impact on the rational quality of public debates.
