Portrait von Julian Kunkel Prof. Dr.Julian Kunkel

Biography

Prof. Dr. Kunkel is a Professor in High-Performance Computing at the University of Göttingen and the Deputy Head High-Performance Computing at GWDG. Previously, he was a Lecturer at the Computer Science Department at the University of Reading and a postdoc in the research department of the German Climate Computing Center (DKRZ). He manages several research projects revolving around High-Performance Computing and particularly high-performance storage. Julian became interested in the topic of HPC storage in 2003, during his studies of computer science. Besides his main goal to provide efficient and performance-portable I/O, his HPC-related interests are data reduction techniques, performance analysis of parallel applications and parallel I/O, management of cluster systems, cost-efficiency considerations, and the software engineering of scientific software. Dr. Kunkel is a member of many international program committees, he is a founding member of the IO500 benchmarking effort, the Virtual Institute for I/O, and the HPC Certification Forum. He is committed to excellence in research and teaching.
