About me

Hi! I am Jinwoo Jeong, a Ph.D. student in Computer Systems Lab (CSL), Korea University. My advisor is Prof. Jeongseob Ahn.

My research focuses on building efficient serving systems for deep neural networks and large language models (LLMs), especially memory management and serving scheduling in GPU-centric environments.

Feel free to reach out to discuss research, collaborations, or ideas!
