Research Interests

My research group investigates methods to increase energy efficiency across the boundaries of circuits, architecture, and systems. Currently, we are exploring the performance and energy benefits of core heterogeneity in future microprocessor architectures to address increasing power density and DarkSilicon, methods for fast-design exploration, and Power-Agile computing for Android devices. Our recent accomplishments include the Sigil workload profiling tool for classifying communication patterns between functions and threads in software; energy-efficient microarchitecture techniques for out-of-order processors, hardware and operating system support for power-agile computing, and design exploration for next generation chip-multiprocessors with the SynchroTrace multithreaded simulation environment. See the lab website, Power-Aware Computing Lab, for more information.

Short Bio

Dr. Hempstead received a B.S. in computer engineering from Tufts University and his M.S. and Ph.D. in engineering from Harvard University working with Professors David Brooks and Gu-Yeon Wei. Before joining Tufts, Professor Hempstead was an assistant professor at Drexel University. He received an NSF CAREER award in 2014 and the Drexel College of Engineering Excellence in Research Award in 2014. He was honored for his achievements in teaching with the 2014 Drexel University Allen Rothwarf Award for Teaching Excellence given to one junior faculty member a year. He was the winner of the industry sponsored SRC student design contest in 2006 and Best Paper Nominee in HPCA 2012.
