Introduction

I am a PhD student in Graduate school of AI at KAIST (MLAI lab), under the supervision of Prof. Sung Ju Hwang. Previously, I was a Research Intern at Meta Reality Labs.

My research focuses on exploring the physical world through the lens of geometry. In my previous work, I developed diffusion models that incorporate geometric principles to generate structured data such as graphs and data on Riemannian manifolds. These models have been applied to a variety of real-world problems, including drug discovery, protein design, and neural architecture search.

More recently, I have become interested in diffusion-based language models, particularly their capabilities in reasoning and planning.
