Hi, I’m Jui-Chao (Jerry). I recently graduated from National Taiwan Univiersity, where I received my Bachelor’s degree in Electrical Engineering with a minor in Computer Science in June 2025. Currently, I am a research assistant at NTU Computational Learning Lab advised by Prof. Hsuan-Tien Lin. Previously, I was also fortunated to be mentored by Professor Hung-Yi Lee under NTU Speech Lab.

I am interested in diffusion models, alignment problem and multimodal learning. My goal is to develop solutions to steer agents to generate precise and preferred response. My previous research includes test-time alignment on diffusion models, agent system optimization and collaborative filtering.
