Graduate Research Assistant

University of Southern California

Laboratory for Machine Learning, Health and Biomedicine

Advisor: Prof. Ruishan Liu

• Developed AI-driven deimmunization methods for synthetic binders, identifying high-immunogenicity peptide regions and suggesting amino acid substitutions to reduce predicted immunogenicity while preserving binding affinity.
• Built an interactive research pipeline for HLA-specific peptide scanning and population-aware immunogenicity analysis, using FastAPI, Gradio, RabbitMQ, peptide-level score caching, and beam search to support efficient and scalable evaluation.

Undergraduate Researcher

Ewha Womans University

AI Computing Platform Lab

Advisor: Prof. Jaehyeong Sim

• Led research on Fisher-guided layer-adaptive quantization for diffusion models, reducing model size by 49.4% while improving FID by 7%; presented the work at the 2024 IEIE Symposium as a co-first author and presenter.
• Conducted a DDPM interpretability study using Integrated Gradients, GradSHAP, and Occlusion to analyze the model's generation process across timesteps, showing a progression from global outlines to fine details; presented at the KCC 2024 XAI Workshop as the only undergraduate-led team.

PokerBench

Small language model training and evaluation for poker decision-making under uncertainty.

• Fine-tuned Qwen3, LLaMA-3.2, and Gemma variants using QLoRA and LoRA adapters on approximately 560K solver-labeled samples.
• Built an evaluation pipeline for instruction-following under uncertainty, comparing model performance against larger proprietary baselines using Action Accuracy and Exact Match.

TalesRunner

AI-powered storybook generation from user-provided images.

• Developed a generation pipeline combining BLIP-based image captioning, fine-tuned KoT5 story generation, and GPT-4o-assisted text refinement.
• Integrated captions, story text, and user images into downloadable PDF storybooks, validating narrative quality, image-text alignment, and formatting consistency across 100+ test cases.

Jeans

AI-assisted photo editing and sharing service designed for senior users.

• Led a 5-member team in developing AI features including fine-tuned Whisper for Korean dialect speech recognition and YOLO/FaceNet-based facial recognition.
• Deployed FastAPI-based ML inference services on AWS EC2 with GitHub Actions CI/CD, refining speech-driven interaction flows through senior user interviews and usability tests.

Software Engineer Intern (Full-stack)

RainbirdGEO

• Developed full-stack features for a weather-forecasting mobile app using React Native and Node.js/Express, supporting pilot deployment and usability testing in Southeast Asian regions.
