About Me

I’m an undergraduate in the Arete Honors Program (AI Biomedical Major) at National Yang Ming Chiao Tung University (NYCU) 🇹🇼, admitted through Special Selection for my achievements in NLP and ML. Alongside my studies, I currently serve as President of Google Developer Group on Campus (GDGC NYCU) 🎓, and previously worked as an AI Engineer at Tenfold AI ⚖️ until April 2026, where I built legal AI systems with agentic architectures on AWS.

I currently conduct research with Prof. Chia-Mu Yu (NYCU) on LLM Safety. More broadly, my research interests in NLP and AI center on:

  • LLM Agents: Designing agentic frameworks and multi-agent systems where LLMs autonomously plan, reason, and collaborate through structured interaction.
  • LLM Safety: Studying adversarial robustness, backdoor vulnerabilities, and safety alignment in large language models.

I also enjoy ML/DS competitions and am drawn to interdisciplinary applications of AI across Biomedicine, Law, and Data Science.
