About Me

I am currently a Dual-degree PhD student in Software Engineering, supervised by Prof. He Jiang , at the School of Software in Dalian University of Technology (DUT), and in Computer Science, supervised by Prof. Lingxiao Jiang and Prof. Xuhua Ding , at the School of Computing and Information Systems in Singapore Management University (SMU).

"To err is human, but to really foul things up you need a computer."

- Paul R. Ehrlich

Software systems written by humans tend to be unreliable and insecure. My research interests focus on developing practical techniques and tools that can help improve the reliability and security of software systems (mainly system software such as compilers and Linux kernels). I am quite interested in developing advanced automated approaches, based on program analysis techniques such as fuzzing and symbolic execution, to resolve labor-intensive engineering tasks, e.g., automatic bug finding and exploit generation.
