Hello! I am a Ph.D. candidate at the University of California, Merced, where I have been working with Prof. Dong Li in the PASA Lab since 2023.

My research focuses on optimizing LLM systems and operating systems with emerging memory technologies (e.g., CXL memory).

Outside of research, I enjoy snowboarding ๐Ÿ‚, working out ๐Ÿ‹๏ธโ€โ™€๏ธ, tennis ๐ŸŽพ, climbing ๐Ÿง—โ€โ™€๏ธ, and surfing ๐Ÿ„โ€โ™€๏ธ. When Iโ€™m away from campus and the office, you might find me hanging out in the snowy mountains, on a tennis court, or at a climbing gym.

Research Interests

  • Memory systems: CXL memory, memory tiering, and programmable OS memory management.
  • LLM infrastructure: inference across heterogeneous processors and memory tiers.
  • Parallel computing: shared-memory communication and scalable scientific workloads.
