Dr. Gabriel Zachmann is professor for computer graphics, visual computing, and virtual reality at University of Bremen, Germany. He is the head of the computer graphics lab since 2012. Before that, he established and headed the computer graphics group at Clausthal University, Germany, where he was a professor with the computer science department since 2005.

Prior to that, he was assistant professor with Prof. Reinhard Klein's computer graphics group at Bonn University, Germany, and head of the research group (Nachwuchsgruppe) for novel interaction methods in virtual prototyping, which was funded by the DFG within the Emmy-Noether programme ("Aktionsplan Informatik").

In 2000, Dr. Zachmann received a PhD in computer science, and in 1994 a Dipl.-Inform (MSc), both from Darmstadt University. He worked on his Diploma thesis during a half-year visit to the National Center for Supercomputing Applications (NCSA) in Urbana-Champaign, Illinois. He began his studies of computer science at Karlsruhe University.

From 1994 until 2001, he was with the Virtual Reality group at the Fraunhofer Institute for Computer Graphics in Darmstadt, where he carried out many industrial projects in the area of virtual prototyping. He also helped found a spin-off (VRCom) that maintains and further develops the VR-System, of which Dr. Zachmann was one of the principal architects during these years. Overall, he was one of the pioneers in Europe who helped develop first Virtual Reality applications for the automotive manufacturing domain.

In 2010, Prof. Zachmann became a Visiting Professor with the Nanyang Technological University, Singapore. From 2009 through 2014, he also served on the board of experts of the "Innovationsallianz Virtuelle Techniken (IA VT)", which was established by the German Ministry for Education and Research (BMBF) within its IKT 2020 framework.

Dr. Zachmann's research interests include geometric algorithms for computer graphics, in particular proximity computations and 3D acceleration data structures, massively-parallel algorithms on the GPU, virtual medical simulation, virtual twins, and virtual prototyping, algorithms in haptics and force-feedback, immersive 3D user interaction, immersive visualization, and others.

Zachmann has published many papers at international conferences in areas like collision detection, virtual prototyping, intuitive interaction, mesh processing, and camera-based hand tracking. He has also served on numerous program committees, as a reviewer for journals, conferences, and publishers, and as a referee for many PhDs, both national and international.

Each year, Prof. Zachmann serves on many international program committees and contributes actively to the organization of conferences such as IEEE VR and VisWeek.

He also served as expert reviewer for the EU to monitor an FP6 project, as a member of the review panel "Information and Communication Technologies" for the Cyprus Research Promotion Foundation (RPF), and on the Review Panel in the Human Brain Project for the Competitive Call for additional project partners. And, of course, he has also served as a reviewer for many funding agencies, such as the DFG (German Research Foundation), the Israel Science Foundation (ISF), the Austrian Science Foundation (FFG), and the Investitions- und Strukturbank Rheinland-Pfalz (ISB).
