Hello! I am an incoming graduate student at COCO Lab, advised by Hyunwoo Kim. I received my bachelor's degree in Economics and Computer Science from Yonsei University.

As AI drives changes at an unprecedented speed and scale, I aim to build safer AI that can navigate the complexity of real-world human interactions. I believe in building AI that is not only capable, but safe and beneficial for society. I work on evaluating and enhancing how AI systems reason socially and cognitively, integrating interdisciplinary insights from behavioural economics and cognitive science to develop robust and context-aware models. I am also passionate about reaching those who are technologically or socially neglected, such as improving AI capabilities for low-resource languages or leveraging AI for mental well-being.

Research Experience

COCO Lab @ KAIST AI April 2026 –

I will be joining COCO Lab as a graduate student in Autumn 2026. I will be exploring problems at the intersection of AI safety, human cognition, and behaviour.

PI Lab @ SNU Mar 2025 – Feb 2026

I dived into my growing interest in misalignment and social reasoning. I experienced what it means to wrestle with a problem that is hard to define — humor, which shifts drastically with social context.

ToC Lab @ Yonsei Jan 2024 – Mar 2025

ToC Lab gave me, a student who only learnt OOP and data structures, the opportunity to intern. I learnt the basics of NLP and did research on detecting LLM-generated Korean text, during which I analyzed synthetic Korean text for months!

Work Experience

NextGen AI Data Engineer Jun 2025 – Sept 2025

I conducted market research and worked on synthetic data construction, inspection, and self-refining pipeline development at an AI startup.

Teaching Experience

Yonsei University Teaching Assistant Sept 2024 – Feb 2026
  • Major Philosophers (UIC 3643)
  • Critical Reasoning (UIC 2101)

After taking his course on ancient Greek philosophy, Prof. Casey McCoy kindly offered me a TA position. I got to have exciting conversations with him about the life of an academic and got a little taste of it myself!

About Me

I enjoy coming up with new dad jokes (or as I argue, MZ jokes) in my free time. I have an endless repertoire and love sharing them with others. Recently, my sister and I visited Hong Kong. When I asked how she liked the hotel room, she said in her British accent, "Sofa so good!" I had to disagree though, the sofa was rock-hard. 🤷🏻‍♀️
