About

I am Full Professor at the Department of Informatics at the University of Minho, and senior researcher at the High Assurance Software Laboratory (HASLab INESC TEC). Since October 2016, I am also serving as Deputy Head of UNU-EGOV, the United Nations University Operational Unit on Policy-driven Electronic Governance (egov.unu.edu).

My research interests are focused on program semantics and calculi applied to systems understanding and rigorous software construction. I am particularly interested in coalgebra theory and conductive reasoning, as well as on modal and hybrid logics.

In recent years I coordinated four research projects at the national level, bilateral partnerships with Brazil and China, and served as the Portuguese coordinator for the Language Engineering and Rigorous Software Development ALFA EU-Latin America network, a PhD training network funded by the European Union. I have published five book chapters, 25 journal papers and more than 60 international conference papers. Having served as invited lecturer in MSc and PhD programmes at the Universities of Bristol (United Kingdom), Tartu (Estonia), and Peking (China), I have supervised several PhD projects (six concluded; four on-going). One of my students, Alexandre Madeira, received the 2013 IBM Scientific Prize, the biggest award in Informatics in Portugal.

I integrated the founding team of the Joint Doctoral Programme in Computer Science of the Universities of Minho, Aveiro, and Porto (MAP-i), and served as its Director. I am a member of IFIP WG1.3 (Foundations of System Specification), and, since January 2019, chair of IFIP Tecnhical Committee TC1 on Foundations of Computer Science.

Currently, I am leading the Quantum Software Engineering Research Group at INL, the International Iberian Nanotechnology Laboratory.

Fuzzy Automata as Coalgebras

Abstract
The coalgebraic method is of great significance to research in process algebra, modal logic, object-oriented design and component-based software engineering. In recent years, fuzzy control has been widely used in many fields, such as handwriting recognition and the control of robots or air conditioners. It is then an interesting topic to analyze the behavior of fuzzy automata from a coalgebraic point of view. This paper models different types of fuzzy automata as coalgebras with a monad structure capturing fuzzy behavior. Based on the coalgebraic models, we can define a notion of fuzzy language and consider several versions of bisimulation for fuzzy automata. A group of combinators is defined to compose fuzzy automata of two branches: state transition and output function. A case study illustrates the coalgebraic models proposed and their composition.

A component-based framework for certification of components in a cloud of HPC services

Publication
Science of Computer Programming

Abstract
HPC Shelf is a proposal of a cloud computing platform to provide component-oriented services for High Performance Computing (HPC) applications. This paper presents a Verification-as-a-Service (VaaS) framework for component certification on HPC Shelf. Certification is aimed at providing higher confidence that components of parallel computing systems of HPC Shelf behave as expected according to one or more requirements expressed in their contracts. To this end, new abstractions are introduced, starting with certifier components. They are designed to inspect other components and verify them for different types of functional, non-functional and behavioral requirements. The certification framework is naturally based on parallel computing techniques to speed up verification tasks. © 2019

Simulation of Nonradiative Energy Transfer in Photosynthetic Systems Using a Quantum Computer

Abstract
Photosynthesis is an important and complex physical process in nature, whose comprehensive understanding would have many relevant industrial applications, for instance, in the field of energy production. In this paper, we propose a quantum algorithm for the simulation of the excitonic transport of energy, occurring in the first stage of the process of photosynthesis. The algorithm takes in account the quantum and environmental effects (pure dephasing), influencing the quantum transport. We performed quantum simulations of such phenomena, for a proof of concept scenario, in an actual quantum computer, IBM Q, of 5 qubits. We validate the results with the Haken-Ströbl model and discuss the influence of environmental parameters on the efficiency of the energy transport.
