I am currently fulfilling my alternative military service as an Algorithm Engineer at GenGenAI, where I focus on generating realistic synthetic data, working closely with Suhwan Cho.

My research focuses on the intersection of 3D computer vision and generative models, developing methods to create realistic synthetic data for downstream tasks.

I completed my M.S at Seoul National University and my B.A. at the University of Virginia both in computer science. During my M.S, I was fortunate to be part of the Visual Computing Lab under the supervision of Hanbyul Joo. Previously, I have worked at SECERN AI, working on Animatable 3D Human Avatars.
