Dr.-Ing. Dominik Wodniok

Graphics Engineer

I'm a Senior Engineer at Qualcomm, Cork, Ireland, working with future GPUs. Previously, I worked as a Graphics Engineer at Gritworld GmbH, Frankfurt, Germany, conducting realtime graphics research and development. Before that, I was a PhD Student in the Graphics, Capture, and Massively Parallel Computing Group of Michael Goesele at TU Darmstadt, where I also was a Research Associate. During that time I worked on computer graphics problems with a focus on ray tracing acceleration structures.

This site provides information on my reasearch and public code. Feel free to contact me if you have any questions.
