    Georgios Papaioannou is currently an assistant professor at the Department of Informatics of the Athens University of Economics and Business (Computer Graphics and Graphical User Interfaces). He was born at Athens, Greece in 1974, received a 4-year BSc in Computer Science in 1996 and a PhD degree in Computer Graphics and Shape Analysis in 2001, both from the National and Kapodestrian University of Athens, Greece.

    From 2002 till 2007 he has worked as a virtual reality software engineer at the Foundation of the Hellenic World (FHW) and has actively participated in the design and implementation of the virtual reality dome theatre system of FHW (Hellenic Cosmos). From 2006 till 2010 he was a lecturer at the Department of Informatics of the Athens University of Economics and Business. Since 1997, he has participated in 19 research and development projects funded by the EU, Greek and university research grants as a researcher, developer, work package coordinator and principal investigator.

    The research of Prof. Georgios Papaioannou is focused on real-time computer graphics algorithms, photorealistic rendering and three-dimensional shape analysis. He has published more than 60 scientific papers in international journals and conference proceedings with peer review and book chapters in the above research areas and has co-authored 3 computer graphics textbooks (1 international, 2 Greek). He is currently actively conducting research in the domains of real-time global illumination, inverse lighting and opening design problems and registration methods for 3D data.

    Georgios Papaioannou is the head of the AUEB Computer Graphics Group, a part of the Multimedia and Mobile Laboratory research unit. Its members conduct research on key areas related to image synthesis, and shape analysis with an emphasis on real-time and interactive applications, as well as work to establish national and international collaborations with institutions and companies for promoting advances in computer graphics techniques, rendering architectures and geometry processing. The AUEB Computer Graphics Group is active and present in major international computer graphics events (e.g. Eurographics, i3D, HPG, Pacific Graphics, etc.) and its research has been positively greeted by the industry.

    Georgios Papaioannou is also a member of ACM, SIGGRAPH and Eurographics Association and has been a member of the program committees of many conferences in the field of computer graphics and 3D data processing.
