Summary
|
He is currently full professor at the Computer Science department of the University of Crete, Greece, associated faculty member at FORTH-ICS with the Human Computer Interaction Lab and visiting professor at the University of Geneva. Prior to this post, he had worked as lecturer, senior researcher and research assistant at MIRALab, University of Geneva with Prof. Nadia Magnenat-Thalmann. He has also held positions as lead computer graphics programmer, CTO and CEO in virtual reality simulation startups. In 2016 he co-founded ORamaVR, a deep-technology spatial computing medical VR training startup with the mission to accelerate world’s transition to medical virtual reality. He is leading ORamaVR as CEO/CTO today. His research and development interests are centered in the field of high-fidelity interactive computer graphics systems for human computer interaction, featuring embodied presence, psychomotor learning and gamification with simulated virtual humans in extended reality based on geometric algebra computational models. Research questions are driven from experiential medical VR training to virtual heritage, and from geometric algebra GPU computational simulation to intelligent, symbiotic extended reality systems for virtual humans and immersive analytics for scientific visualization. He has more than 100 publications in the field, over 2250 citations and h-index 26 (January 2022). He is a board member of the Computer Graphics Society (CGS) and member of the IEEE, ACM, Eurographics and SIGGRAPH professional societies. He is associate editor of the Springer Visual Computer Journal, research topic lead editor of the Frontiers in Virtual Reality Journal and evaluator/reviewer for the European Commission and several National Research Funding agencies worldwide. In 2011 he has been awarded with a Marie-Curie Intra-European Fellowship for Career Development from the European Commission’s Research Executive Agency. In 2016 he served as Conference Chair of the Computer Graphics International (CGI’16) annual conference (one of the leading and oldest computer graphics conferences) and in 2020 as programme co-chair. Under the auspices of CGI and CGS he co-founded in 2016 the ENGAGE: Empowering Novel Geometric Algebra for Graphics and Engineering Workshop running annually ever since. In 2017 he published a Springer-Nature book on Mixed Reality and Gamification which achieved more than 70.000 downloads so far, reaching the top 25% most downloaded eBooks on Springer-Nature for 2020. He is currently supervising 2 post-doc, 6 PhD, 2 MSc and several BSc final year students. His research above has attracted direct contribution of more than €3.3M EU R&D/industrial funding. |
