Dr. Christian Engelmann is an R&D Staff Scientist in the Computer Science Research Group at Oak Ridge National Laboratory. He has 15 years experience in software research and development for extreme-scale high-performance computing (HPC) systems with a strong funding and publication record. In collaboration with other laboratories and universities, Dr. Engelmann’s research solves computer science challenges in HPC software, such as scalability, dependability, energy efficiency, and portability. His primary expertise is in HPC resilience, i.e., providing efficiency and correctness in the presence of faults, errors, and failures through avoidance, masking, and recovery. Dr. Engelmann is a leading expert in HPC resilience and a member of the DOE Technical Council on HPC Resilience. He received the 2015 DOE Early Career Award for research in resilience design patterns for extreme scale HPC. His secondary expertise is in lightweight simulation of future-generation extreme-scale supercomputers with millions of processors, studying the impact of hardware and software properties on the key HPC system design factors: performance, resilience, and power consumption. Dr. Engelmann is a member of the Association for Computing Machinery (ACM), the Institute of Electrical and Electronics Engineers (IEEE), and the Advanced Computing Systems Association (USENIX).
