Christian Engelmann is a Senior Computer Scientist at Oak Ridge National Laboratory. He holds a Ph.D. and a M.Sc. in Computer Science, University of Reading, UK, and a Dipl.-Ing. (FH) in Computer Systems Engineering, University of Applied Sciences Berlin. He has 19 years experience in research and development for next-generation high-performance computing (HPC) systems. His research aims at HPC computer science challenges, such as dependability, scalability, and portability. Dr. Engelmann’s primary expertise is in HPC resilience, i.e., providing efficiency and correctness in the presence of faults, errors, and failures. His secondary expertise is in HPC hardware/software co-design through lightweight simulation of extreme-scale systems with millions of processor cores to study the impact of hardware properties on application performance. He published over 100 papers in renowned refereed journals and proceedings of international conferences. He received the 2015 DOE Early Career Award for research in resilience design patterns for extreme scale HPC.
