Research

I'm currently working on hardware-accelerated vortex detection, segmentation and visualization. This research is financed by the German Research Council (DFG) as part of SPP 1147, a nation-wide project involving several universities and other research institutes and scientists both from the fields of fluid dynamics and computer science. Detailed information about the project can be found here.

Teaching

I'm supervising the following two courses (taught in German) in the winter term 2004/2005:

• Fachpraktikum: Graphikprogrammierung
• Hauptseminar: Hierarchische Visualisierungsverfahren

Publications

Prior to working on vortex detection I worked on a number of other topics. Publications about this work can be found on the publications page of the institute. These a some of my images (in chronological order):

From left to right: First remote volume rendering experiment on a Compaq iPAQ; unstructured grid of a highly resolved engine compartment resampled to a hierarchy of Cartesian grids (industry project); vortex structures detected on the GPU; GPU-based extraction of isosurface geometry (triangles and quads); vortices separated from a flow field; volume rendering of human head using GPU-raycasting (combined visualization of transparent isosurfaces and direct volume rendering; see also project page).
