This paper is an outcome of the master's thesis I guided by Anissa Faik. We created a dashboard for teachers to monitor students' performance on a learning platform in real-time. We studied how explanations influence teachers' trust in an algorithm that detects outlier students.

This paper is an outcome of the master's thesis by Joran De Braekeleer, which I guided and Katrien Verbert supervised. We studied how gamification can be used to nudge adolescents towards recommended exercises on a mobile app for practising math equations.

My PhD thesis focuses on human-centred explainable AI and presents 5 studies on how explainability can be established through visual analytics, visualisation-supported justification, and visualisation-supported control.

My paper with Leen Dereu for the IUI 2023 conference. It is based on Leen's master's thesis on a steering mechanism for recommended exercises. We studied how a control mechanism and a visualisation that depicts the control's impact affected adolescents' trust in a platform that recommends mathematics exercises.

My journal paper for Agriculture presents a prototypical visual decision support system that incorporates price prediction, uncertainty, and visual analytics techniques. Interviews and questionnaires suggest that user-centred approaches are key for increasing the uptake of visual decision support systems in agrifood.

My work with Shotallo Kato for the IUI 2022 conference, based on Shotallo's master's thesis. We studied the impact of explanations on adolescents' trust in a platform that recommends maths exercises.

My advanced review for WIREs Data Mining and Knowledge Discovery. It presents current approaches in healthcare for explaining artificial intelligence algorithms with visual analytics.

My paper for the TREX workshop at the IEEE VIS 2021 conference. It is about how domain expertise influences people's trust in prediction models.

A summary of Shotallo Kato's master's thesis, which I guided. The research focused on how explanations for recommended exercises affect adolescents' trust in a mathematics educational platform.

Summary of my contribution to the EU BigDataGrapes project. I created a dashboard that visualises product prices, predicted prices, and uncertainty in the predictions.

My first published paper, presented at the CHI PLAY 2020 conference. The analysis is based on the data that I collected for my Applied Informatics master's thesis.

In my Applied Informatics master's thesis, I studied the impact of tailored gamification in the scope of mathematical education. This article summarises my research.
