Short Bio

Christian Schulz received his Ph.D. in computer science from Karlsruhe Institute of Technology, Germany in 2013. Afterwards he was leading the graph partitioning & parallel processing subgroup in the group of Peter Sanders and later on leading the algorithm engineering subgroup of the group of Monika Henzinger in Vienna. Christian Schulz obtained a habilitation in computer science in 2019 and returned to Germany as a full professor at Heidelberg University. He has more than 100 publications, mostly on algorithms in the context of scalable graph algorithms. This includes multilevel algorithms [(hyper)graph partitioning, clustering, etc.], parallel algorithms [sorting, graph generation, etc.], streaming algorithms, support vector machines, data reductions algorithms as well as dynamic graph algorithms. He received various awards for his research, e.g. the Heinz Billing Prize, the KIT doctoral award, as well as a best paper award at IPDPS, SEA and at IEEE CLUSTER. His codes won several competitions such as the DIMACS Implementation Challenge on Graph Partitioning and Clustering and the PACE Implementation Challenge on Vertex Cover.
