About Me

\Begin{multicols}{2}

{ width=180px }

I am a Ph.D student at Seoul National University (SNU), advised by Byoungyoung Lee in Compsed lab. My primary research areas are hardware fuzzing and cloud computing. Especially, I have worked on implementing RTL fuzzer to find bugs in RISC-V CPU designs. Currently, I am working on secure cloud computing technology, so called confidential computing (e.g., Intel SGX, and AMD SEV). To be specific, I am working on re-designing current big-data, and machine learning platform to protect data while preserving efficiency.
