Research background: I obtained my PhD at KU Leuven (2016, Belgium) focusing on information systems which consisted of 2 parts: (1) Model-Driven Engineering (code generation for soft/web apps including backend/frontend/UI/databases) to support requirements (data and behavior) modeling, simulation/testability, semantic/syntactic validation of business requirements represented as models (UML/XML/text), and (2) model-based cognitive feedback and behavioral feedforward generation based on behavior and process analytics. The output software for generating software included a feedback-enabled platform based on the concepts that are nowadays known as model-based low-code development environment.

Research expertise: My current research areas include process- / behavior- analytics, learning analytics, feedback/recommendation automation and visual analytics dashboards, model-driven engineering and low code, business intelligence and applications, explainable AI, educational technology among others. I am also interested in expanding my domain towards a broader context of digitalization and big data analytics applications in different sectors such as education, government, healthcare, logistics, etc.

Teaching: Currently my teaching areas include (1) (Business) Information Systems and Information Management (2) Business Intelligence topics (e.g. Business analytics, Databases, Big Data and data mining, visual analytics & dashboards, process analytics, text analytics) and (3) Low Code application development.

To be expanded - Low code data mining, high code programming, recommender systems

  • Tutorial presenter:
    • Boosting requirements analysis and validation skills through feedback-enabled semantic prototyping (IEEE RE, 2015)
    • Novel way of training conceptual modeling skills by means of feedback-enabled simulation (ER conference, 2015)

Industry experiences: Next to research in academia, I also combine professional experiences from government, banking and software industries.

Other professional expertise - Software Engineering (5 years in software engineering positions practicing agile methodology + 6 years using programming JAVA, #C and related technologies in daily research activities).

Cross-disciplinary research synergies: Currently I work in the intersection of IEBIS and CODE sections researching shared areas of interest on information and education technologies. Next to UT, I combine research experiences from several other research groups:

  • PhD/postdoc - Information systems / Augment (KU Leuven, Belgium)
  • Research project management - IDLab (imec / UGent, Belgium)
  • Postdoc - KNOW center (Technical University of Graz, Austria)
  • Visiting researcher - Learning and Educational Technology (Oulu University, Finland) ¬†
  • Visiting researcher - Welten Institute Research Centre for Learning, Teaching and Technology (OUNL)

  • Contributor -¬†Redesign4TU:¬†High-tech & data-driven agri-food¬†of the future (4TU project¬†https://www.4tu.nl/redesign/):¬†In the context of this project I contribute to the domain of food recommenders for sustainable food production/consumtion based on data from varied sources such as food domain and healthcare.¬†The significance of food is evident in the myriad challenges confronting contemporary society, including the increasing prevalence of diet-related diseases, food waste with its adverse economic, environmental, and social impacts, and the significant impact of food production on environmental issues, among others. As the negative health and environmental impacts of dietary patterns become more evident, there is a growing demand for personalized and sustainable food recommendations to promote healthier and planet-friendly choices.¬†¬†
  • Principal researcher -¬†How educational feedback needs changed during the times of Covid pandemic and what are the long-term effects?¬† (BMS funding)¬†While it is evident that digitalization will be pivotal for accomplishing a transition to post-pandemics educational environments, where hybrid classroom/campus uniting the physical and digital learning experiences will most likely define the new norms, the field lacks insights to guide informed decisions in the domain of feedback digitalization. Despite the importance of this transition world-wide, still questions such as ‚Äúwhat is the type of digital feedback that worked best during lockdown education?‚ÄĚ, ‚Äúwhich new formats used by teachers proved effective among students?‚ÄĚ, ‚Äúare there preferences in these new formats/elements of feedback to continue even when the lockdown education disappears?‚ÄĚ remain unanswered.¬†
  • TeToMoCo: The goal of the project is three-fold: 1.¬†TeToMoCo (Text-To-Model-To-Code)¬†framework that combines the state-of-the-art natural language processing approaches and techniques for identifying potential architecture elements candidates out of business requirements articulated in natural language textual description. 2. A subsequent prototype implementation that can assist a knowledge construction process through (semi-) automatic generation and validation of UML models. 3. Automatic web application code generation (backend/frontend/UI) out of generated UML/XML models following principles of Model Driven Engineering.

  • CITADEL H2020:¬†CITADEL is a European H2020 Project involving twelve partners. These are research institutes, universities, public sector entities and IT companies from five different European countries. The project‚Äôs objective is to create an ecosystem of best practices for a transparent, innovative and cooperative public sector and to provides more efficient and inclusive tools to respond to citizen requirements. The CITADEL ecosystem combines and promotes a set of technologies (e.g. semantics, mobile, analytics, sentiment analysis, open linked data) to both empower Public Administrations (PAs) to improve their offering and the engagement of citizens, as well as to foster cooperation among PAs and users of public services in local, regional and national environments. Main contributions as a partner included:¬†1. an ecosystem architectural guidelines, 2. design and development of a semantic dashboard to support improving public services for e-government at EU public administration organizations.¬†¬†
