About Me
I am a research scientist at Meta.
I received my Ph.D. degree from KAIST, where I was advised by Prof. Dongsu Han. During my Ph.D., I worked on improving machine learning and networking systems through designing efficient algorithms and implementing system-level optimizations in real-world systems. My contributions have been recognized at numerous top-tier venues, including SIGCOMM, ICML, and EuroSys. I received my B.S. degree in Electrical Engineering from KAIST, Republic of Korea.
