Biography

Stefan Ohrhallinger is a senior researcher 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 Zentrales Melderegister (Central Population Register) for the Ministry of Interior, Austria.

In 2013, he obtained his PhD from Concordia University, Montréal, Canada. Since October 2012, he has been a research associate at TU Wien, working mainly on surface reconstruction, geometry processing, and point-based graphics. He has reviewed for major conferences and journals in Computer Graphics, including TOG, TVCG, SGP, CAG, EGPGV, GI, Sensors, and SIGGRAPH, and served on the IPCs of GCH'18, Eurographics'21, '22, '23, Pacific Graphics'22, '23, '25, and SMI'23, '24, and '25. He co-coordinated Eurographics'21 in Vienna.
