William Nixon

Hello!

I'm William, a 2nd year Ph.D. student in Computer Science at the University of Chicago.

I work on efficient systems for caching, storage, memory management, and LLM serving.

I'm fortunate to be advised by Prof. Haryadi S. Gunawi and Prof. Juncheng Yang.

Feel free to reach out via email, always happy to chat!
