I am a PhD candidate at Sogang University advised by Prof. Moon-Ryul Jung, with coursework completed as of August 2025. My research sits at the intersection of machine learning and underserved domains: music information retrieval, low-resource NLP for ancient languages, motion synthesis, and content safety.
Alongside my graduate studies I spent three years shipping Roblox experiences at Dubit for clients including Viacom, Samsung, and SM Entertainment, among others, and most recently worked as an AI research engineer at Paralov. I hold a BS in Computer Science from Stony Brook University and am a US / South Korean dual citizen based in Seoul.
Publications
Appearance-Invariant Detection of Suggestive Motion via Laban Movement Descriptors on SMPL Skeletons
Extending a multilingual language model to support low-resource languages with unseen scripts (Coptic, Syriac, Gothic, OCS Glagolitic, Samaritan). Results yield 8–106× perplexity reduction over conventional fine-tuning. Paper in preparation.
VBPM (Variational Bar Pointer Model)
Replaces the traditional Dynamic Bayesian Network in beat tracking pipelines with a fully differentiable variational model over structured latent variables, allowing for end-to-end training.
KineGuard
Skeleton-based content safety classifier for real-time unsafe motion detection. Built multi-GPU video processing pipeline with WHAM inference.
