About Me

I am an Applied Research Engineer at Krafton AI, where I work on simulation and agent systems.
I completed my M.S. in AI at KAIST in February 2025, and earned my Bachelor’s degree in Cyber Defense from Korea University.
My current interests are Agentic AI, Social Simulation with AI, and Efficient AI. During my M.S., I focused on efficient deep learning systems and diffusion model quantization. In my undergraduate years, I was active in whitehat hacking and CTF, and served as Vice President of CyKor.
