About me

I am full professor at the Computer Science Department, Universidade do Minho, and a senior researcher at the High Assurance Software laboratory, HASLab INESC TEC. I am a member of IFIP WG1.3 (Foundations of System Specification), and, since January 2019 chair of IFIP Technical Committee TC1, on Foundations of Computer Science. Previously, from 2013 to 2018, I have served as Portugal representative in this Committee.

My main research focuses on program semantics, logics and calculi applied to rigorous software analysis, design, and construction. I am particularly interested in the architectural dimension (interaction, composition, and reconfiguration) of different sorts of software components, namely nondeterministic, probabilistic, quantum, continuous, or hybrid. Most of my work is framed on Coalgebra and Modal Logic.

More recently I became interested in exploring connections between Physics and Computation at two levels: the discrete-continuous frontier and the classic-quantum interaction. In this context, I joined INL, the International Iberian Nanotechnology Laboratory, in the Quantum and Linear Optical Computation Group. With Ina Schaefer (KIT), I started in 2022 a new IFIP working group WG 1.11/2.17 on Foundations of Quantum Computation.

I have a second academic affiliation to the United Nations University, currently serving as Deputy Head of its Operational Unit on Policy-driven Electronic Governance. UNU-EGOV is an international think-tank devoted to multidisciplinary research on how digital transformation may contribute to empowered democratic citizenship, trustworthy public infrastructures, more inclusive societies and, in broad terms, to sustainable development.

Above all, I am very fortunate to work with an amazing team of students and post-docs. Our joint research is framed in the Logic and Formal Methods group.

Position statement

Software technology is pre-scientific in its lack of sound mathematical foundations to provide an effective basis to predict and certify programs' behaviour. Compared to other Engineering disciplines, we are somewhere in the 17th century. My research aims at improving scientific standards, seeking rigour and simplicity in software design and architecture through Mathematics.

A proper roadmap for a true Software Engineering discipline, targeting either classical, cyber-physical or quantum systems, has to discuss how systems are modelled and composed, and how properties of their behaviours are anticipated, expressed and verified.

As K. Lewin once put it, `there is nothing so practical as a good theory´.
