I am a Research Officer at the Agency for Defense Development (ADD), Korea's national defense R&D agency (similar to DARPA), and a First Lieutenant in the Republic of Korea Air Force.
I work on LLM serving in heterogeneous clusters and efficient vision inference. I'm fortunate to have Prof. Olivia Hsu (CMU) and Prof. Jongse Park (KAIST) as research mentors. Previously, I worked on memory bug detection and fuzzing at UNIST S2Lab under Prof. Yuseok Jeon (Korea University).
I am applying to Ph.D. programs for Fall 2027, with research interests in computer architecture and systems for AI.
IEEE S&P 2025
The first CMA-aware address sanitizer designed to detect memory bugs in objects allocated by custom memory allocators. CMASan discovered 19 security vulnerabilities, including 7 CVEs: CVE-2023-7104, CVE-2023-7152, CVE-2023-7158, CVE-2024-8946, CVE-2024-8947, CVE-2024-8948, and CVE-2024-11235.
NeurIPS 2025
A training-free strategy for accelerating diffusion sampling by treating classifier-free guidance as a multirate system.
IISWC 2026
Identifies diagonal attention sparsity in autoregressive image generation induced by spatial locality, and exploits it with a diagonal-aware sparse attention mechanism that improves throughput by up to 3.1× with negligible quality loss.
IISWC 2026 (Short Paper)
Characterizes GPU-to-PIM replacement tradeoffs in multi-turn agent serving and evaluates session-KV residency as a second-tier prefix cache, reducing energy by up to 78% and latency by up to 67%.
