Computer Architect · Meta Infra Silicon

I am a Computer Architect and ASIC Engineer on the Infra Silicon team at Meta. I earned my M.S. & Ph.D. from Yonsei University (advised by Prof. Won Woo Ro), specializing in GPU microarchitecture, memory subsystem optimization, and computing resource efficiency for large-scale AI workloads.

My background includes system architecture research for SmartNIC DPUs at MangoBoost, visiting research at UC Riverside, and joint hardware development projects with Samsung and SK Hynix.
