I am currently fulfilling my alternative military service as an Algorithm Engineer at GenGenAI, where I focus on generating synthetic data with 3D. 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.
