Jeong Woo Lee

I will join the University of California, Irvine as a Master of Computer Science student in Fall 2026. I completed my B.S. in Electronics and Electrical Engineering at Dongguk University, where I researched table and chart reasoning for LLMs and VLMs at ML-Lab, advised by Prof. Jihie Kim. This work led to five papers, including an ACL Workshop Best Paper (TabBridge). Alongside research, I've shipped a full-stack AI web service end to end (E-MOJI) and open-sourced a table reasoning tool built on Ollama. I'm interested in understanding both the strengths and limitations of AI systems, and in how human insight can be designed into them to address those limitations. Feel free to reach out via GitHub or email.

Experience

ML-Lab, Dongguk University — Undergraduate Research Assistant
Advisor: Prof. Jihie Kim · Seoul, KR

Led research on structured data reasoning, designing TabBridge (bridging table structure and context for LLM reasoning) and co-developing VisDoT (decomposed visual reasoning for VLMs); first-authored four of five published papers and received an ACL Workshop Best Paper Award. Along the way, built and open-sourced a table reasoning tool on Ollama to run table reasoning experiments on local LLMs without API costs.

Research

TabBridge — LLM Table Reasoning

Text-to-SQL table reasoning fails when question terms don't match table headers, generating queries over columns that don't exist. TabBridge bridges the table's structure and the question's context through TabSpec, a verified intermediate representation, reaching 73.94% on WikiTableQuestions (+5.3pp over prior SOTA).

VisDoT — VLM Chart Reasoning

LVLMs fail on chart questions with visual referents like "leftmost bar" or "dark red" because they cannot ground visual elements to their meaning — and chain-of-thought doesn't help when the model looks at the wrong place. VisDoT forces perception before logic, decomposing questions into perception-first sub-questions grounded in graphical perception theory, outperforming GPT-4o with 20× less training data than prior methods.

Projects

E-MOJI — Personalized AI Emoji Web Service
Leader & Full-Stack Developer · Seoul, KR · GitHub

Led full-stack development (onboarding non-developer teammates onto core Django APIs) and deployed on AWS EC2 with Prometheus-Grafana monitoring; offloaded slow AI image generation to Celery workers via RabbitMQ, using Redis for status polling.

ReBike — Smart Waste Detection Website
Front-end Developer · Seoul, KR · GitHub

Built the React client (migrated JavaScript to TypeScript mid-project) and annotated a custom waste-image dataset to train a YOLOv5 model, building the detection UI that renders returned bounding boxes and class labels.

Leadership & Teaching

Dongguk University — Undergraduate Teaching Assistant
Machine Learning & Deep Learning Courses · Seoul, KR

Mentored 30+ students through office hours, clarifying core ML/DL concepts and providing feedback on project deliverables; awarded TA Scholarship.
