👋 Call me Joshua.

🎓 I’m a first-year CS Ph.D. student at CSAIL, MIT EECS, advised by Samuel Madden. I’m a member of MIT CSAIL Everest Lab and LMCache Lab. I have been fortunate to work with Omar Khattab, Junchen Jiang, Ravi Netravali, Kexin Pei, and Ganesh Ananthanarayanan. Previously, I graduated from the University of Chicago with B.S. in Mathematics and Computer Science.

👨‍💻 My research interests lie broadly in computer systems and artificial intelligence. I build more efficient, reliable systems to improve ML/AI workloads, e.g., agentic context management, AI query engines for deep research, and KV cache management.

In a fruitful and diverse previous life, I was a research engineer on the founding team of Tensormesh (creator of LMCache). During my undergraduate years, I began research in mathematics, advised by Gregory Lawler and Jinwoo Sung, and worked on probability theory.

Feel free to shoot me an email to talk about anything. I am always open to collaborations and working with undergraduate/master’s students. Check out Collaborations for details.
