Integration Systems Modeling and Analysis
Integration Systems is a research topic and as such has received significant attention from the research community over the last years. The main motivation is the growing need for data exchange and reuse of functionality between applications in the context of enterprise software. These applications support business processes and are commonly not designed and developed to collaborate. Decentralised technologies such as blockchains integrated with smart contracts are emerging technologies aimed at the decentralisation of systems and applications that are unnecessarily centralised; they bring innovative ideas and concepts that have the potential to facilitate the development of disruptive decentralised systems and applications that are more scalable, reliable and secure. Examples, of such applications are Decentralised Finances (DeFi) based on unregulated and regulated cryptocurrencies, such as Bitcoin and CBDC (Central Bank Digital Currencies), respectively. This research line investigates the application of blockchain and smart contracts in the context of integration processes modelling and implementation. We investigate how to formally express contractual agreements to be able to detect accidental or intentional violations to the agreed commitments, programatically. Specific topics of interests include Domain-specific languages for writing smart contracts used in integration systems, performance analysis and optimisation of runtime engines that compose the integration systems.

Data Integration and Analysis
Data Science is an interdisciplinary area that combines computer science, domain expertise, statistics and math to extract knowledge from normally heterogeneous and large volumes of data retrieved from different sources. This research line investigates methods, processes, techniques, algorithms and tools to extract useful information from raw data available from different data sources. We are interested in developing applications for data integration, data mining and data analysis applied primarily in the domains of health, education and agriculture. In our research, we follow a computational approach that takes advantage of latest advances in artificial intelligence (IA), Internet of Things (IoT), big data, data analytics, decision support systems, machine learning, and recommender systems.

Software Engineering
The current Internet is full of software systems that have been supporting the daily activities of people and organisations for decades. These systems are becoming increasingly network-connected, complex, large and insecure; to exacerbate the problem, they have to operate in dynamic environments that are continuously afflicted by changes. The development and maintenance of these systems is a challenge and has motivated software developers to adopt a systematic, organised, and quantifiable approach. In this research avenue, our research group studies methodologies, techniques, general-purpose and domain-specific languages for the modelling and developing high-quality software systems. We also investigate software reuse, software quality assurance, software evolution, and experiment languages such as Java, Python, PHP, Javascript for web, desktop, and mobile applications.
