--  I am currently Full Professor at the Faculty of Exact Sciences and Engineering (FCEE) at the University of Madeira (UMa), and Head of the Department of Informatics Engineering and Interactive Media Design.

In terms of education I obtained a Bachelor’s degree in Computer Science from the University of Buenos Aires (UBA), Argentina, in 1991. I then pursued a PhD in Computer Science, summa cum laude, at the same institution, graduating in 1999. In 2008, I received my Habilitation (Agregação) in Informatics Engineering, specialising in Artificial Intelligence, from the University of Madeira. In 2011, I completed a second PhD in Philosophy at the Royal Institute of Technology (KTH), Sweden.

I have been a Full Professor at the University of Madeira since 2020, having joined the institution as an Assistant Professor in 2002. Prior to this, I was an Assistant Professor at the Department of Computer Science at the University of Buenos Aires (UBA) from 1997 to 2002, and held teaching assistant roles between 1991 and 1997, primarily in the fields of Artificial Intelligence and Logic.

Over the years, I have held various academic governance roles. From 2020 to 2024, I was a Member of the General Council of the University of Madeira, contributing to institutional policy and strategic planning within the university’s main governing body.
I served as Head of the Department of Informatics Engineering and Interactive Media Design at the University of Madeira during 2016--2019, 2021--2022, and from 2025 onwards. My responsibilities included curriculum development, faculty recruitment, and departmental management. I was also Head of the Department of Mathematics and Engineering from 2008 to 2009.
I coordinated two research poles: Madeira-ITI (2010--2011), where I chaired the Scientific Council, and Madeira N-LINCS (2020--2022), focused on knowledge transfer and collaborative research.

Since 1991, I have taught at several universities, including the University of Madeira, the University of Buenos Aires, and the University of São Paulo, across undergraduate, master's, and doctoral levels. My teaching has covered a broad range of subjects, including Artificial Intelligence, Logic, Software Engineering, and Decision Theory, within programmes in Computer Science, Informatics Engineering, Mathematics, and related fields.

I have supervised 4 postdoctoral researchers, 6 doctoral theses, and 33 master's dissertations, as well as numerous undergraduate final projects and theses. My supervision spans various programmes, including Informatics Engineering, Mathematics, Psychology, Mathematics Education, and Computer Science, at institutions such as the University of Madeira, University of Coimbra, and University of Buenos Aires. The research areas covered include Artificial Intelligence, Belief Revision, Neurorehabilitation, Educational Robotics, Profile Dynamics, Machine Learning, and Knowledge Representation.

My research is primarily focused on Belief Revision (Logic of Theory Change), which addresses how systems integrate new information. I began working in this area in 1988 during my undergraduate studies. My work has involved the development of theoretical frameworks and, more recently, the application of belief revision algorithms to support consistent updates in systems, such as in neurorehabilitation therapy and recommendation system dynamics. I also research in Knowledge Representation and reasoning and Non-Monotonic.

Since 1997, I have led ten scientific projects and contributed as a senior researcher to five others. These projects were funded by institutions in Portugal, Argentina, Brazil, France, Germany, and the wider European region. They focus on belief revision, cognitive systems, and the application of formal methods in artificial intelligence within domains such as neurorehabilitation.

I have been an integrated member of the NOVA Laboratory for Computer Science and Informatics (NOVA LINCS) since 2012 and am the founder of its pole at the University of Madeira, Madeira N-LINCS.
I have participated in numerous national and international research groups, including founding and coordinating units. My affiliations span institutions in Portugal, Brazil, and Argentina, within FCT research centres and thematic laboratories focusing on Artificial Intelligence, Knowledge Representation, and Logic for Artificial Intelligence.

I have undertaken over 40 short-term research visits to institutions across Europe, Latin America, Asia, and the USA. \newline These visits, ranging from one week to several months, involved collaborations with departments in Computer Science, Artificial Intelligence, and Philosophy.

I contribute to the international AI research community through editorial, review, and academic selection activities. I serve on the editorial boards of journals such as Argument and Computation, Journal of Applied Logics, CAAI Transactions on Intelligence Technology, and Inteligencia Artificial. I have reviewed research proposals for institutions including COST (EU), the Latvian Council of Science, South Africa’s National Research Foundation, FAPESP (Brazil), and various universities and research organisations across Europe and Latin America. I have also served on numerous academic selection committees and doctoral examination boards in Europe, South America, and Asia.
I have held organisational roles in several international events. I have chaired or co-chaired conferences such as JELIA, NMR, and IBERAMIA, and I founded the BRAON workshop series (Belief Revision, Argumentation, Ontologies and Norms). I regularly serve on programme committees for major AI conferences, including IJCAI, AAAI, ECAI, JELIA, and KR, often as a Senior PC member or Track Chair.

I am co-author of the book Belief Change: Introduction and Overview (Springer, 2018) and the forthcoming volume Non-Prioritised Belief Change (Springer, 2025). I have also served as editor of conference proceedings and special journal issues, including Trends in Belief Revision and Argumentation Dynamics and JELIA 2014.
I have published over 40 peer-reviewed journal articles, including contributions to journals such as the Artificial Intelligence Journal (5 articles), Journal of Artificial Intelligence Research, ACM Transactions on Computational Logic, Journal of Symbolic Logic, and Journal of Philosophical Logic (4 articles).
In addition, I have authored or co-authored more than 40 refereed conference papers, presented at major venues such as AAAI, IJCAI, ECAI, and KR. My research centres on Belief Revision, Knowledge Representation, and Non-Monotonic Logic, with applications in automated reasoning, adaptive decision-making, and AI for neurorehabilitation.

I have delivered over 30 invited talks and tutorials at universities and international scientific events. These include keynote lectures, tutorials, and invited seminars across Europe, the USA, Latin America, Oceania, and Asia. Notably, I have conducted tutorials at leading conferences such as IJCAI, ECAI, andKR.
I have been invited to speak at events including the 1st South African Workshop on Knowledge Representation (Cape-KR 2024), the 17th European Conference on Symbolic and Quantitative Approaches to Reasoning with Uncertainty (ECSQARU 2023), the 3rd Workshop on Proof Theory and its Applications, the Conventicle at the 16th Pacific Rim International Conference on Artificial Intelligence (PRICAI 2019), and the 18th Brazilian Logic Conference.
