Current lab members


Jan Aerts
Full professor

Jan has a background in genetics and genomics, and performed his doctoral research at the University of Wageningen (Netherlands) on the Chicken Genome Sequencing Project. He then moved to Scotland to work as a postdoctoral researcher at the Roslin Institute on the Cow Genome Sequencing Project. Next, he continued his research at the Wellcome Trust Sanger Institute near Cambridge (UK) focusing on structural variation in the human and other primate genomes. At his return to Belgium at the KU Leuven in 2010 (as assistent and later associate professor), he shifted focus to data visualization and visual analytics, with the aim of finding interesting questions in large datasets (big data). His main research topics revolve around visual design, interaction design, and (human and computational) scalability. Since 2019, he is professor at Hasselt University where he continues his visual analytics work and helps build a new Data Science Institute.

Jan has been on the organising committees of several conferences (including BioVis and Beyond The Genome), and has chaired visualization-related sessions at conferences including VIZBI, the Bioinformatics Open Source Conference BOSC and EuroVis/VMLS. He is also Associate Editor for the BioMedCentral Thematic Series on Biological Data Visualization, and academic editor for PLoS One. He was founding member of the Young Academy – Royal Flemish Academy of Belgium for Sciences and the Arts.

She currently works under the main supervison of Katrien Verbert and Koenraad Brosens on the visual representation of social networks in the domain of art history. Houda has a bachelor’s degree in Computer Science from Al Akhawayn University in Ifrane, Morocco, and a joint Masters degree in Human-Computer Interaction from the ENAC and the Université Paul Sabatier in Toulouse, France.

Alumni


Thomas Moerman
PhD student

Thomas is a PhD student at both the Universiteit Antwerpen and KU Leuven (joint PhD). His PhD research focuses on scalable implementations of interactive visualization and analysis tools for hypothesis-free exploration of complex data. Thomas worked as a software engineering and architecture consultant in a broad spectrum of industries, where he built systems ranging from back-end data systems to mobile apps. With more than a decade’s worth of battle scars as a professional programmer, he seeks to apply his experience in the scientific domain. He is a strong advocate of the functional programming paradigm. Thomas obtained a Master’s degree in Informatics in 2002 and an Advanced Master’s degree in Artificial Intelligence in 2003 at the KU Leuven.


Thomas De Bodt
PhD student

Thomas has a background in computer science. His research focus is using visual analytics on location data to enable insight generation. This has many applications, for example early identification of illegal activity at sea or improving people flow in a train station. This project is a collaboration between KULeuven and Luciad. Thomas has worked for 8 years as an R&D software engineer at Luciad, designing and realizing a high-performance visualization library for geospatial data. Through this research Luciad wants to scale its technology to the huge amount of location data available today.


Jansi Thiyagarajan
PhD student

Jansi has a techno-functional background. She obtained her Bachelor degree in Electrical Engineering from Anna University in India and a Master degree in International Business from ESC Grenoble in France. She started her career as a marketer and then moved to the area of commercial data analytics owing to her interest in making sense of data to drive business. She strongly believes that visualisation is the most effective way to communicate the insights and finds it exciting to visualise data from different domains. Her current research focuses on visualising genomic and healthcare data.


Jaume Nualart
