Dr. Pieter Jorissen finished his computer sciences studies at the Limburg University Center, now known as Hasselt University Belgium, in July 2001. Thereafter, he started working as a researcher at the Expertise Center for Digital Media (EDM) which is the multimedia research center of the UHasselt and is a partner in the IBBT, a Flemish research initiative.

He worked at the EDM for approximately 6 years on several research projects concerning Collaborative Virtual Environments. In January 2008, he obtained his Ph.D. with his dissertation "Dynamic Interactions for Networked Virtual Environments."

In 2008 he mainly worked as a Researcher/Consultant on new technologies and information security for Smals, a large Belgian IT company mostly focusing on supporting the social security administration and eGovernment. His main task was to follow up on new technologies and find ways to implement them for the government administration.

In 2009 he left research and development to start a career as a lecturer at the Karel de Grote University College. He focuses on teaching how to program and build 3D interactive applications. He has also been active as an international program committee member for several computer graphics and virtual reality conferences.

Dr. Sebastian T. Koenig received his Ph.D. in Human Interface Technology from the University of Canterbury, New Zealand, developing a framework for individualized virtual reality cognitive rehabilitation. He obtained his degree as Diploma-Psychologist from the University of Regensburg, Germany, in the areas of Clinical Neuropsychology and Virtual Reality Rehabilitation.

Dr. Koenig is currently working as a Research Associate at the USC Institute for Creative Technologies, where he designs, develops, and tests clinical virtual reality software.

He also works as Lead User Researcher for the game development company Red 5 Studios and as a freelance software engineer and cognitive psychologist to develop mobile applications and cognitive assessments for the US military and health care companies.

His professional experience spans over ten years of clinical work in cognitive rehabilitation and over five years of virtual reality research, development, and user testing. Dr. Koenig has extensive experience as a speaker at international conferences and as reviewer of scientific publications in the areas of Rehabilitation, Cognitive Psychology, Neuropsychology, Software Engineering, Game Development, Games User Research, and Virtual Reality.

Dr. Koenig has developed numerous software applications for cognitive assessment and training. For his work on the Virtual Memory Task he was awarded the Laval Virtual Award 2011, in the category "Medicine and Health." Other applications include the virtual reality executive function assessment in collaboration with the Kessler Foundation Research Center and the patent-pending Microsoft Kinect-based motor and cognitive training JewelMine/Mystic Isle at the USC Institute for Creative Technologies.

Dr. Koenig maintains the website www.virtualgamelab.com about his research and his software development projects. His website also contains a comprehensive list of tutorials for the game engine Unity.
