About

I am Chenyuan Yang (杨晨源), a PhD student at UIUC advised by Prof. Lingming Zhang since 2022 Fall.

I received my B.S. degree with honors from the elite program in the Department of Computer Science & Technology at Nanjing University, advised by Prof. Yanyan Jiang.

My research focuses on enhancing the reliability of software systems, such as machine learning systems, compilers, and OS kernels. To achieve this, I employ a combination of testing, analysis, and verification techniques, with a particular emphasis on leveraging the power of large language models (LLMs).

To date, my work has uncovered over 400 previously unknown bugs in widely-used machine learning systems, including PyTorch, TensorFlow, JAX, as well as 9 CVEs for the Linux kernel.

Besides deep learning systems and the Linux kernel, I also reported more than 30 bugs for other open-source projects, such as NumPy, Moby, and VSCode-Vim.
