Marcel Ritter studies Computer Science and Civil Engineering at the University of Innsbruck, Austria. After gaining his Master of Computer Science in 2010, he worked on the research project Airborne Hydromapping at the Unit for Hydraulic Engineering. In 2012 he joined the Doctoral School DK+ Computational Interdisciplinary Modeling pursuing a PhD in Computer Science affiliated to the Unit for Strength of Materials and Structural Analysis. There he was also acting as lecturer in practical courses on solving statically indeterminate systems. He joined the Interactive Graphics and Simulation Group (IGS) in 2015, where he is currently working as PostDoc after graduating in 2021. During his studies, he maintained collaborations to several foreign research groups. He worked as a research staff member at the Center for Computation and Technology at the Louisiana State University, USA, in 2008. Also, he visited the Professorship for Graphical Computing at the Goethe University of Frankfurt in 2014 and 2016. Beside his academic activities, he co-founded the gaming company Clockstone GmbH in 2007 and the Airborne Hydromapping Software GmbH in 2014 - dedicated to bathymetric LiDAR data analysis and visualization. He worked (part-time) in those companies as 2D/3D graphics artist, level designer, programmer, scientist, and head of software developement, during his studies, and currently supports part-time at AHM and Eloaded GmbH. In his free time, he enjoys playing the bassoon in ensembles such as the University Orchestra Innsbruck or the traditional wind band Stadtmusikkapelle Innsbruck Wilten.
