AI undergraduate student at Gachon University, interested in building and analyzing intelligent systems around large language models, multimodal AI, reasoning, and world models.
I enjoy turning research ideas into working pipelines, especially when they involve model behavior analysis, safety alignment, Korean NLP, and multimodal interaction.

| Project | What I Worked On | Keywords |
|---|---|---|
| Transferable System Prompt via Activation Signatures | Built a pipeline for prompt evaluation, hidden-state extraction, and activation-based analysis on Llama and Gemma to study prompt transfer across GSM8K, CSQA, SVAMP, and BoolQ. | LLM analysis, activation signatures, prompt transfer |
| Value-Aligned LLM Safety Validation | Reproduced a VIM / LoRA-based value alignment pipeline on Mistral-7B and benchmarked category-wise safety risks on BeaverTails and HEx-PHI. | LLM safety, alignment, LoRA |
| MUTON: Real-Time Multimodal Dialogue System | Built a streaming multimodal dialogue system with facial affect recognition, PCM audio streaming, Transformer fusion/generation, and Qwen2.5-Omni LoRA fine-tuning. | Multimodal AI, dialogue, Qwen |
| Korean Dialogue KG Construction & Reasoning | Developed an event/causal extraction pipeline, ATOMIC triple generation/translation, KG integration, R-GCN inference, and KG-enhanced LLM reasoning. | Korean NLP, knowledge graph, reasoning |
| Korean AI-Generated Text Detection System | Implemented a machine-generated text detection pipeline using KoELECTRA and KoBigBird with chunk voting and logit averaging. | Korean NLP, text detection, transformers |
| Momentrip | Developed a Jetpack Compose Android app for personalized travel recommendation and itinerary planning. | Android, recommendation, planning |
