About

I am a Combined Master and Ph.D. student at UNIST, advised by Prof. Hyungon Moon. My research focuses on building secure and efficient system architectures. I aim to fundamentally mitigate memory corruption vulnerabilities at the OS level while optimizing resource isolation.

Research Interests

System Security Operating Systems Memory Management Program Analysis
Study Notes Public notes on systems, security, memory management, and paper reading.

Research Experience

Feb 2020 – Present
Memory Allocator for Temporal Safety

Designed and implemented HushVac and HushVac+, efficiently mitigating Use-After-Free (UAF) vulnerabilities. Collaborated on SwiftSweeper, a sweeping architecture eliminating stop-the-world pauses. Pioneered early work on OS-assisted UAF prevention on Glibc (MarKern).

Jan 2024 – Feb 2025
In-Storage Computing Architectures

Developed SODE, a mechanism for selective on-device execution of data-dependent read I/Os to optimize storage operations.

Dec 2025 – Mar 2026
Serverless Computing Optimization

Collaborated on FaaSlim, optimizing serverless computing through partial caching of snapshot-based VMs.
