About

I am a first-year CS PhD student at University of Virginia, advised by Prof. Yu Meng. I am fortunate to be supported by UVA Provost's Fellowship and UVA Computer Science Scholar Fellowship.

Previously, I was a research assistant at MiuLab, National Taiwan University, advised by Prof. Yun-Nung (Vivian) Chen. I obtained a MS in Computer Science at National Taiwan University, advised by Prof. Hsin-Hsi Chen and a BS in Computer Science at National Yang Ming Chiao Tung University.

My current research interests broadly lie in AI safety and evaluation in the era of LLMs. I have also worked on denoising retrieval-augmented generation, metigating hallucination in text generation, and eliciting zero-shot capability in LLMs.
