Research profile


I am a postdoc researcher at the 3D geoinformation group of the Delft University of Technology in the Netherlands. I am also the secretary of the ISPRS working group IV/1 on Multi-dimensional modelling.

Visit my homepage for more information.


My research covers various aspects of geographic information, with a focus on the use of novel techniques to process data geometrically and topologically. These include: higher-dimensional (4D and higher) data structures and algorithms, GeoBIM integration, the validation and repair of geographic data, and visualising spatial data. I like theoretical work, but what I enjoy most is implementing my ideas into working prototypes and, when they are serious enough, into free software.
