The Visualization and Graphics Group (VIG), led by prof. dr. Alexandru C. Telea, creates visual analysis tools and methods to help scientists and researchers better process and understand large, multi-dimensional, and relational datasets in various domains such as neuroscience, genomics, software engineering, astronomy, and medicine.
Our mission is to empower experts, as well as non-data scientists, to solve Big Data problems through Visualizations, Interaction Concepts, Data Mining techniques, and Realistic Rendering methods.
VIG is part of the Department of Information and Computing Science, Utrecht University.
- visualization for AI (dimensionality reduction, explaining machine learning)
- big data multiscale visualization (hierarchies, graphs, trails, tables)
- visualization in practice (decision making, user studies)
- information visualization and visual analytics (techniques, system design, evaluation)
- photorealistic computer graphics (techniques, evaluation)
- shape/image processing (skeletonization, segmentation, fairing, reconstruction)
- scientific visualization (fluid simulation, GPU- and PDE-based techniques)

We teach (and taught) many courses spanning all areas of visualization and graphics and for different audiences (BSc/MSc/PhD students, professionals). Details here.
We have supervised many students at all levels (BSc/MSc/PhD). Selected key results here.
Research valorization
Our work has led to two innovative start-ups
