I am a Senior Researcher in computer science, specialized in 3D computer graphics and visualization. I have studied computer science at TU Wien, where I received my PhD on the topic of dynamic and probabilistic point-cloud processing in 2017. Since 2018 I am with the Institute of Computer Graphics and Knowledge Visualization at the Faculty for Computer Science and Biomedical Engineering of Graz University of Technology, working on projects of applied geometry processing and interactive visualization. My main research interests include probabilistic geometry processing and representation, rendering and visualization.
