Yunbo Ni

I am a first-year PhD student at the Department of Computer Science and Engineering, The Chinese University of Hong Kong (CUHK). I am fortunate to be advised by Prof. Shaohua Li. These days, I spend most of my time thinking about how to break compilers (on purpose), especially using large language models as part of the testing process. I'm also curious about how LLMs understand and generate code — and what that means for future tools built on top of them. As an undergraduate student, I studied Software Engineering at the Nanjing University.

For any inquiries, feel free to reach out to me via mail!

Awards: In 2022, I received the National Scholarship from Chinese Ministry of Education in Nanjing University (top 1%). In 2024, I received Joyce M. Kuok Scholarship (￥10,000) from Nanjing University. In 2025, I won second place in the ACM Student Research Competition at SPLASH 2025.
