I'm chairing the Algorithms, Geometry, and Applications (ALGA) cluster at the Department of Mathematics and Computer Science of TU Eindhoven.

Research Interests

Algorithms and data structures; discrete and computational geometry; applications of computational geometry to geographic information systems, geo-visualization and visual analytics, and e-Humanities.

This video (from 2011) is an attempt to explain my research interests to a broader audience ... hover the images below for some more examples.

Honors

From 2010 until 2015 I was a member of The Young Academy (De Jonge Akademie) of the Royal Netherlands Academy of Arts and Sciences (Koninklijke Nederlandse Akademie van Wetenschappen). From 2011 to 2016 I was a member of the Global Young Academy. In 2011 I won the first Netherlands Prize for ICT Research (see here for some more details in Dutch). Part of the prize was a poster which gives a high-level impression of my work and was sent to high schools all over the Netherlands.

Organization

I am a member of the Computational Geometry Steering Committee.
I co-organized CG week 2015, which included the 31st International Symposium on Computational Geometry (SoCG 2015), in Eindhoven, June 22-25, 2015.
I co-organized the 19th International Symposium on Graph Drawing (GD 2011) in Eindhoven, September 21-23, 2011.
I co-organized the 21st European Workshop on Computational Geometry (EuroCG 2005) in Eindhoven, March 9-11, 2005.

Historical Remarks

Before I came to Eindhoven I was a postdoc in the Combinatorics, Geometry and Computation European Graduate Program at ETH Zurich. In Zurich I was a member of the Theory of Combinatorial Algorithms group headed by Emo Welzl. I received my Ph.D. from the University of British Columbia in Vancouver, Canada, where I was supervised by David Kirkpatrick and Jack Snoeyink.
