About
I am an incoming M.S. student at KAIST FlexML Lab, advised by Prof. Insu Han. I joined the lab in September 2026 and will begin the M.S. program in Spring 2027. I am currently finishing my B.S. in Computer Science at KAIST.
My research interests are AI agents and the decision models behind them. Much of an agent's work is not writing but deciding: which tool to call, where to route a request, whether a step succeeded. I am interested in models built for these decisions, such as Jev, which return typed choices with calibrated confidence instead of free-form text.
Before joining FlexML, I studied efficient attention and LLM agents at the SIIT Lab under Prof. Junmo Kim and spent a semester at the Technical University of Denmark studying computer vision. Outside the lab, I built LLM-based services as an intern at NewXphere and, before that, interned at Penta Security, where I saw firsthand how web security and cryptography research is done.

Research experience
Efficient attention and LLM agents
2025 – Aug 2026Studied RoPE-based positional encodings and linear attention, comparing their long-context behavior and compute–memory trade-offs with standard softmax attention. Surveyed LLM agents with a focus on memory, planning, tool use, reasoning, and test-time computation.
Cost and score metrics for object detection
2024Studied evaluation metrics for object detectors, including mAP and OC-cost. Proposed a modified OC-cost formulation and compared it with the original metric across multiple models.
High-efficiency wet air purification system
2020 – 2021Developed and operated a high-efficiency wet air purification device. The work won the Gold Prize at the 18th Korea Science and Engineering Fair and was selected to represent Korea at Regeneron ISEF.
