About

I'm currently a post-doctoral researcher at the HASLab unit of INESC TEC at the University of Minho, Portugal.

I've recently completed my joint PhD degree on computer science from the Universities of Minho, Aveiro and Porto, on a "Relational Approach to Bidirectional Transformation" under the supervision of Professor Alcino Cunha.

My research focuses on bridging the gap between formal methods and software engineering through the development of lightweight approaches and techniques, with the goal of improving the overall quality of software products. Current research topics include trustworthy software design frameworks and safety validation of robotic software.

Validating the Hybrid ERTMS/ETCS Level 3 concept with Electrum

Authors
Cunha, A; Macedo, N;

Publication
International Journal on Software Tools for Technology Transfer

Abstract
This paper reports on the development of a formal model for the Hybrid ERTMS/ETCS Level 3 concept in Electrum, a lightweight formal specification language that extends Alloy with mutable relations and temporal logic operators. We show how Electrum and its Analyzer can be used to perform scenario exploration to validate this model, namely to check that all the operational scenarios described in the reference document are admissible, and to reason about expected safety properties, which can be easily specified and model checked for arbitrary track configurations. We also show how the Analyzer can be used to depict scenarios (and counter-examples) in a graphical notation that is logic-agnostic, making them understandable by stakeholders without expertise in formal specification. © 2019, Springer-Verlag GmbH Germany, part of Springer Nature.

Static-Time Extraction and Analysis of the ROS Computation Graph

Abstract
The Robot Operating System (ROS) is one of the most popular open source robotic frameworks, and has contributed significantly to the fast development of robotics. Even though ROS provides many ready-made components, a robotic system is inherently complex, in particular regarding the architecture and orchestration of such components. Availability and analysis of a system's architecture at compile time is fundamental to ease comprehension and development of higher-quality software. However, ROS developers have to overcome this complexity relying mostly on testing and runtime visualisers. This work aims to enhance static-time support by proposing, firstly, a metamodel to describe the software architecture of ROS systems (the ROS Computation Graph) and, secondly, model extraction and visualisation tools for such architectural models. The provided tools allow users to specify custom-made queries over these models, enabling the static verification of relevant properties that had to be (manually) checked at runtime before. © 2019 IEEE.
