About Me
Hi, I’m Seyeon Choi, a PhD student at Seoul National University, affiliated with the Vision & Learning Lab. My research focuses on building generalizable embodied agents, with particular interest in grounding, interaction, and decision-making in complex environments.
I am currently exploring how large language models can move beyond static reasoning to act robustly as agents, especially under distribution shifts and unseen environments. My long-term goal is to develop agents that integrate symbolic reasoning with reinforcement learning to enable flexible, human-like behavior across diverse settings.
I have research experience across vision, language, and agent systems through internships and projects at multiple labs, and I enjoy translating theoretical ideas into practical, scalable systems.

Ludo Robotics
Intern
September 2026 – October 2026
Participated in the BEHAVIOR Challenge 2026.
Seoul National University
Research Intern
Advised by Gunhee Kim
July 2024 – Feb 2025
Out-of-domain generalization for web agents. Studied why web agents degrade on unseen websites and how training data should be selected to close that gap, leading to Weasel (ICML 2026).
Co-led the LLM subgroup of an accessibility-focused AI docent project. Worked with Heeseung Yun to manage five researchers and deploy RAG-based systems across three major museums in Seoul; the project was featured at the Korea Metaverse Festival.

A Little More About Me
Outside of my research, I enjoy activities that help me recharge and stay curious.
- Cooking, especially Asian cuisine
- Exploring new restaurants and cafés ☕️
- Collecting and enjoying fragrances, with a preference for citrus 🍋🟩, floral 🌸, and soft musk notes
- Reading books in my spare time 📚
