Stefan Ohrhallinger is a Postdoc researcher at the VRVis Research Center for Virtual Reality and Visualization and leading the project "Superhumans - Walking through Walls" (FWF) in cooperation with Michael Wimmer from the research group "Rendering and Modeling" ( at the Institute of Visual Computing and Human-Centered Technology ( at TU Wien, Austria. He graduated with a Master of Business Informatics (Wirtschaftsinformatik) in 1997 from Johannes-Kepler University Linz, Austria. From 1990 to 2009 he developed software for various projects in Austria, the United States, and Canada, e.g. as the software architect for the central population registry (Zentrales Melderegister) for the Ministry of Interior, Austria.

In 2013 he obtained his Ph.D. from Concordia University, Montréal, Canada. From 2012 to 2019 he worked as a research associate at TU Wien on surface reconstruction, geometry processing, and point-based graphics. Projects include Harvest4D (EU, 7th Framework Programme) and Real-Time Shape Acquisition with Sensor-Specific Precision (FWF). He has reviewed for major conferences and journals in Computer Graphics, including TOG, TVCG, SGP, CAG, EGPGV, GI, Sensors, and served on the IPC of GCH'18.
