Research Description

Professor Sherwood's research is in the area of computer architecture, specifically in the development of novel high throughput hardware and software methods by which systems can be monitored and analyzed. Such techniques provide a powerful new way to inspect and control the digital world --- they shed light on performance anomalies, uncover software bugs, and help secure critical systems against attack. His students work across all layers of the hardware/software stack, from circuits to software application, and his prior work on phase analysis has seen adoption by many major manufactures to help them design and analyze their processors.

Biography

Before joining UCSB in 2003, Sherwood received his B.S from UC Davis (1998) and his M.S. and Ph.D. from UC San Diego (2003) where he worked with Professor Brad Calder. In his short time with UCSB, Professor Sherwood has received the 3 consecutive IEEE Micro Top Pick Awards for novel contributions significant to industry, and an NSF CAREER award in 2005. His prior work on Program Phase Analysis methods (a technique for reasoning about and predicting the behavior of programs over time -- a critical step in reducing power consumption) has been cited over 350 times and is now used by Intel, HP, and other industry partners to guide the design of their largest microprocessors.
