I am a final-year CS Ph.D. student at the University of Illinois at Urbana-Champaign, advised by Prof. Marc Snir and Prof. Jian Huang. My research focuses on computer systems, specifically building efficient and reliable storage systems using machine learning. I work across the entire storage systems stack, from storage devices like SSDs to file systems and cloud storage infrastructure.

News
