About

I’m Woohyung Choi (최우형, 崔宇亨), a Ph.D student at Computer Systems Laboratory (CSL), Korea University.

My current research is focused on LLM Serving Systems. I am broadly interested in computer systems, especially those that support modern AI workloads.

I received my master’s degree in Artificial Intelligence from Ajou University under the supervision of Prof. Jeongseob Ahn. I also hold a B.E. degree in Digital Media from Ajou University.
