Christian leads the Representation and Planning (RAP) area at PARC. The stated mission for this area is to “Build, mature, and deploy innovative software that addresses previously unmet market needs by leveraging and advancing state-of-the-art representation and planning techniques.” Current focus is on applications in digital manufacturing and urban transportation. In both of these areas we expect significant disruptions to occur over the next 5-10 years, from 3D printing in the former and self-driving cars in the latter. We contribute to these opportunities by means of developing and implementing algorithms that are needed to realize the full potential of these disruptive technologies. Christian earned his Ph.D. in Computer Science from the Knowledge Representation group at the University of Toronto, Canada, and his M.S. and B.S. degrees in Computer Science from RWTH Aachen, Germany. Christian’s interests are in classical artificial intelligence, knowledge representation, automated planning and search, execution monitoring, and machine learning. Christian joined PARC in 2010, and has been co-PI on the iFab project as well as on the follow on project in DARPA’s iFAB Foundry program. Christian has served as a product owner and development manager for this project, which has led to the uFab software for automated process planning.
