I am a Research Assistant Professor in the College of Computing at Illinois Tech, where I work closely with Prof. Xian-He Sun at Gnosis Research Center. My research spans several areas in Computer Architecture and High-Performance Systems, with a particular focus on optimizing memory hierarchies, enhancing data-centric designs, leveraging AI to improve system performance, and enabling efficient algorithm-hardware co-design.
