I am part of the 'Smart Worlds' area at the VRVis Research Center in the group 'Geospatial Rendering'. I am responsible for the development of PRo3D, an interactive 3D visualization tool for planetary scientists in the context of collaborations with ESA and NASA. Further, I also lead the development of TSID, a 3D viewer for tunnel surface inspection and documentation, in collaboration with dibit Messtechnik GmbH. I am also doing my PhD at the Technische Universität Wien combining the two worlds of Visual Analytics and Real-Time Rendering. In addition, I supervise bachelor and master students, who support my research efforts, and I am also experienced in writing grant applications.

Software Engineer & Researcher, VRVis, Vienna, PRo3D
In the context of several projects concerned with the exploration of Mars (Exomars, PRoViDE, MastCamZ) we developed the 3D real-time rendering application PRo3D  which allows the exploration of and interaction with high resolution, digitally-reconstructed 3D surfaces provided by Joanneum Research Graz. PRo3D supports interactions for virtual geological annotations, which are already extensively used by domain scientists [4,5,6] and we are also addressing other planetary science use cases.

Ph.D. Student, VRVis, Vienna, VISAR - Visual Analytics and Rendering.
This fundamental research project was concerned with the seamless integration of 3D spatial and non-spatial data, by combining 3D real-time visualizations and information visualization views. This integration becomes increasingly relevant in fields, such as, civil engineering, urban planning, or disaster management, to only name a few. We published a conceptual framework  and two design studies in the context of 3D visibility analysis  and lighting design .
|2008 - 2012||
Software Engineer & Researcher, VRVis, Vienna, Dibit7.
Development of the core visualization component within a tunnel documentation application in collaboration with Dibit Messtechnik GmbH. and Joanneum Research Graz. This involved the out-of-core rendering of and the interaction with large triangulated datasets at interactive frame rates, as well as appropriate visualizations of additional abstract data and domain-specific interaction metaphors [7, 8].
Various Internships, VRVis, Vienna.
(1) Design and implementation of an out-of-core point rendering framework. (2) Supporting migration of a 3D real-time rendering application from VC++ 4.0 to VC++ 6.0. (3) Design and implementation of a mesh splitting algorithm.
