I am currently a MS/PhD student at Seoul National University (SNU), advised by Hanbyul Joo.
My research primarily focuses on 3D digital human modeling through the lens of generative models, with a particular interest in compositional modeling.
Recently, I’ve been expanding my interest toward human-environment interaction, which naturally extends to robotics. My long-term goal is to bridge digital human simulation with real-world robotics to enable collaborative agents.

Sep. 2026Our work HOPE was accepted to NeurIPS 2026.
We factor action realization and robot appearance out of the world model by rendering actions as visible robot geometry, yielding a shared visual interface that transfers across viewpoints and unseen robot embodiments.
HOPE estimates temporally evolving per-vertex pressure and contact on a hand mesh directly from monocular RGB video, transferring from gloved-hand supervision to bare-hand egocentric and in-the-wild interactions.
HRDexDB is a large-scale, multi-modal dataset of 2.1K paired human and robotic hand grasping trials with high-precision 3D annotations, serving as a benchmark for cross-embodiment dexterous manipulation.
Vanast tackles virtual try-on with human image animation via synthetic triplet supervision, generating identity-preserving, pose-driven try-on videos from a person image and one or more garment references.
The first method for generating portrait animation videos with facial attribute transfer from a given reference image to a target portrait in a zero-shot manner.
We present HairCUP, a universal prior model for 3D head avatars with hair compositionality, which enables hairstyle swapping and efficient personalization.
We present Guess The Unseen, a method to reconstruct the world and multiple dynamic humans in 3D from a monocular video input.
