About me

Howdy! I am an incoming Ph.D. student in Computer Science at the University of Minnesota. I am currently working with Prof. Zirui Liu on machine learning and systems.

My recent projects explore LLM determinism in training and inference and elastic KV cache for efficient GPU memory utilization. Broadly, I enjoy investigating the intersection of algorithms and systems to make AI more capable, more efficient, and more reliable.

I am always open to new discussions and collaborations. If you have ideas or questions you’d like to share, feel free to reach out!
