Hi👋! I am a Project Assistant and PhD Candidate at the Institute of Software Engineering and Artificial Intelligence of Graz University of Technology (TU Graz), Austria, working on Knowledge-based Diagnosis, Configuration Systems, Software Product Lines, and Explanations in AI.

Under the supervision of Professor Alexander Felfernig, my doctoral research — Intelligent Techniques for Efficient Diagnostic Reasoning in Constraint-Based Systems — develops solver-agnostic algorithms for conflict detection, diagnosis, and quality assurance that scale to industrial constraint-based systems, including configuration systems and recommender systems. More recent work extends these foundations toward causality-based explanations and Large Language Models for Software Product Line Engineering.

Before joining TU Graz in 2020, I spent more than 15 years at the University of Economics, Hue University, Vietnam, as Lecturer and Vice-Dean (2014–2019) of the Faculty of Economic Information Systems, teaching Programming, and Data Structures and Algorithms, while researching Recommender Systems and Information Visualization, particularly multi-agent models for visualizing relationships in collaborative filtering. I obtained my Master of Computer Science (2008–2011) at the Institute for Informatics in French-speaking areas, Vietnam, with double diplomas from the University of La Rochelle, France, and Hanoi University of Science and Technology, Vietnam. During my Master’s study, I worked on Machine Learning, Content-based Information Retrieval, and Information Visualization, and completed my Master’s thesis — an image browser based on Self-Organizing Maps — as part of an internship at the Catholic University of Louvain, Belgium, under the supervision of Professor Michel Verleysen.

I am now looking forward to research positions in academia and industry where I can continue working on Explainability, Knowledge-based Reasoning, Constraint Acquisition, and the integration of symbolic and learning-based methods.
