I hold an appointment as full professor in Visual Data Analytics at the Department of Information and Computing Sciences, Utrecht University. Before this, I worked as full professor of Multiscale Visual Analytics in the (SVCG) group at the Bernoulli Institute, Faculty of Science and Engineering, University of Groningen.

Research focus

  • information visualization and visual analytics (techniques, system design)
  • big data multiscale visualization (large hierarchies, graphs, trail sets)
  • visualization for AI (dimensionality reduction, explaining machine learning)
  • shape/image processing (skeletonization, segmentation, fairing, reconstruction)
  • interactive systems design (interaction and animation for data exploration)
  • scientific visualization (GPU-based and PDE-based visualization techniques)
  • program analysis (reverse engineering, software evolution, fact extraction and querying)

The Book: Data Visualization - Principles and Practice

My book (2nd edition published by CRC Press) gives a practical introduction to data visualization. It targets (under)graduate students and professionals interested in designing and implementing visualization applications to explore big data. Topics covered: scalar, vector, tensor, image, volume, and information visualization.

New in the 2nd edition: C/C++ code samples, exam questions, projects, datasets, and ParaView scenarios.

First edition: 2008. Second edition: 2014. Chinese edition: 2018. Over 5000 copies sold (2018).

PhD Research

My PhD research (2000) was on the design and implementation of VISSION, an application building environment for VIsualization and SImulation with Object-oriented Networks. VISSION offers object-oriented tools for scientific visualization and real-time interaction with running simulations, is easily extendable with user code, and creates visual programming tools and GUIs automatically from object-oriented code. VISSION proved (relevant at the time) that all one can achieve in Java can also be done in C++, only better, cleaner, and easier.

Research valorization

My work led to a successful (>2M EUR turnover) start-up company (SolidSource BV) specialized in tools and services for the visual analysis of big data for industry-scale software maintenance.
