About
I do research in Computer Architecture, with a focus on memory system performance. My research has introduced novel ways to improve hardware caching and prefetching. I am the inventor of the Hawkeye cache replacement policy, which won the 2017 Cache Replacement Championship. My current research focus is to make machine learning a viable tool for computer architects.
