In the last years my focal point of research was on flow visualization. As a project member of the
DFG Schwerpunktprogramm 1147: Bildgebende Messverfahren für die Strömungsanalyse (imaging methods for experimental flow measurements) I did some work in 2D and 3D real-time
flow visualization, texture-based techniques, flow feature extraction and visualization.
However, beside flow visualization, I did also some research in real-time computer graphics, like planetary terrain rendering, point-based rendering, and applications of (non-)linear ray tracing.
To obtain an inpression of the results achieved in the last years, I refer to the images
and the respective publications.
I expect to finish my PhD by the end of 2008.
