I am an Associate Professor in the Reasoning and Argumentation Lab, NOVA Institute of Philosophy and the Department of Communication, NOVA University Lisbon. After dual master's training (philosophy, communication) I received my PhD in Humanities – Argumentation Theory from the University of Amsterdam (UvA) in 2010. From 2010 to 2016 I worked as a post-doctoral fellow of the Portuguese Foundation for Science and Technology (FCT), and then as an Assistant Professor between 2016 and 2023. 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. Within this range of issues, I apply philosophical concepts of (practical) rationality, speech acts, and various forms of disagreement to study the mechanisms and norms of public argumentation, with a focus on potential abuses of language in the socially important contexts of environmental, health, and broadly political controversies. I teach Philosophy / Theory of Communication, Argumentation, and Methodology courses and supervise PhD students and post-doc researchers. As the Main Proposer and Action Chair, I lead the COST Action project CA17132, "European Network for Argumentation and Public Policy Analysis" (APPLY, 2018-2023, € 772.707), where philosophical and linguistic concepts and methods were 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, and from 2021-2024, a PI of the Portuguese team of the CHIST-ERA project "Argumentation-driven explainable artificial intelligence for digital medicine" (ANTIDOTE: CHIST-ERA/002/2019). 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). In 2023 I published a monograph "Argumentation in Complex Communication" with the Cambridge University Press, (co-authored with Mark Aakhus, Rutgers University), the winner of the 2023 “Distinguished Book Award” (Book of the Year) of the Philosophy of Communication Division of the National Communication Association. My current research revolves around the issues of plural and duplicitous speech acts, verbal and conceptual disagreements, explanations and explanatory dialogues, the concept of argument, and the challenges of online communication to our theories of (rational) conversation. All these lines of work converge on the question of the rational quality of public debates. I have regularly published and edited volumes and special issues of journals with main academic publishers such as Cambridge University Press, Springer Nature, and John Benjamins. As of 2023, I serve as an Associate Editor of "Topoi: An International Review of Philosophy", responsible for its "Philosophy of Argument" Section. I am a member of the Editorial Board of "Argumentation" (Springer) and "Argumentation and Advocacy" (Routledge). I seat on the five-person Ethics Committee of the School of Social Sciences and Humanities of the NOVA University Lisbon (NOVA FCSH).
