I’m a University Assistant/PhD Student at the Institute of Visual Computing, Graz University of Technology. I work on city-scale reconstruction using Gaussian Splatting, supervised by Markus Steinberger.
Previously, I received my Master’s degree in Computer Science (with distinction) and my Bachelor’s degree in Computer Science both at Graz University of Technology between 2019 and 2024. During this time, I worked as a study assistant, supporting various visual computing and alorithm classes.
My research interests include Radiance Fields, GPU algorithms and Geometry Processing.
