Hello,

 안녕하세요

[📣 2025 June Update] I will be joining KAIST AI as an Assistant Professor starting in 2026, where I will lead the Computation & Cognition (COCO) Lab. I will be taking 2~3 students (M.S., M.S.+Ph.D., Ph.D.; 석사, 석박통합, 박사). If you are interested in joining my lab, please tell me a bit about yourself using this form!

I'm currently a Postdoctoral Researcher working with Yejin Choi at NVIDIA for my gap year. Previously, I was a Young Investigator and an intern at the Allen Institute for AI (Ai2). I received my Ph.D. in Computer Science from Seoul National University, advised by Gunhee Kim.

My research goal is to enhance machines’ cognitive capabilities through computational methods, focusing on social reasoning (e.g., theory of mind), formal reasoning (e.g., knowledge-intensive domains), and interactive agents guided by these abilities. To achieve this, I explore three key directions: optimizing inference-time compute, synthesizing large-scale data, and evaluating cognitive behaviors. Additionally, I am interested in taking an interdisciplinary approach to my research, bridging AI and cognitive science. In particular, I like to distill insights from human development and cognition into models for reasoning.
