 I hold an appointment as full professor in Scientific Visualization and Computer Graphics at the Institute Johann Bernoulli, University of Groningen, the Netherlands.


My interests cover the following:



scientific visualization (flow visualization, GPU-based acceleration techniques)

information visualization (software visualization, InfoVis systems design)

multiscale visualization (hierarchical data representations and visual metaphors)

interactive systems design (visual application builders, dataflow environments)
multivariate visualization (dimensionality reduction, multivariate projection exploration, categorical data)
computer imaging (skeletonization, medical imaging, PDE-based image processing)
object-oriented and component-oriented software design (design and architectural patterns)
static source code analysis (reverse engineering, C/C++ parser design, fact extraction and querying)

Data Visualization: Principles and Practice (2nd edition, 610 pages)

This second edition of the book originally published in 2008 provides a practical introduction to data visualization.
It addresses (under)graduate students and professionals interested in designing and implementing visualization
applications to explore and understand data in a range of fields, including computational flow dynamics,
engineering sciences, medical imaging, geometric modeling, and software engineering.
Topics covered: scalar, vector, tensor, image, volume, and information visualization.

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

Published by CRC Press in 2014.

PhD Research

My PhD research was on the design and implementation of VISSION, an interactive 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 application-specific modules, and constructs visual programming and graphics user interfaces automatically for object-oriented application code.
