Craig Philip Steffen serves as a Senior Research Scientist at the National Center for Supercomputing Applications (NCSA), University of Illinois Urbana-Champaign, focusing on hardware acceleration and energy-efficient computing architectures within high-performance computing environments. His research expertise spans GPU computing, Field-Programmable Gate Array (FPGA) acceleration, and energy efficiency optimization. Steffen has pioneered methodologies for power measurement in large-scale systems and developed the EcoG architecture for power-efficient GPU clusters. His work addresses critical challenges in balancing computational performance with energy constraints, particularly for scientific workloads requiring heterogeneous computing solutions. Analysis of his 2007-2014 publications reveals an evolutionary research trajectory: beginning with reconfigurable computing foundations, progressing through FPGA acceleration techniques, and culminating in comprehensive GPU cluster optimization and power measurement frameworks. This progression mirrors the industry's growing emphasis on energy-aware design as supercomputing systems scale toward exascale capabilities. As part of NCSA's interdisciplinary research ecosystem, Steffen collaborates within teams developing advanced computational infrastructure that supports national scientific research initiatives across diverse domains.
