Biography

Stefan Ohrhallinger is a Postdoc 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 Ministery of Interior, Austria.

In 2013 he obtained his PhD from Concordia University, Montréal, Canada. Since October 2012 he is 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 served on the IPC of GCH'18. He will serve as Co-located Events Chair for Eurographics'2021 in Vienna.
