Biography

I earned my Ph.D. in Computer Science from Concordia University, Montreal, Canada, in 2024, under the supervision of Dr. Tse-Hsun (Peter) Chen. I also hold a bachelor's degree in Computer Science and a master's degree in Software Engineering. My research focuses on software engineering, including software analysis, testing, mining software repositories, and empirical software engineering. I am particularly interested in improving the quality and performance of modern architectural applications, such as database-backed applications and mobile applications. Recently, I have expanded my work to AI4SE, applying advanced techniques like natural language processing (NLP), computer vision (CV), large language models (LLMs), and vision-language models (VLMs) for software engineering tasks. Before pursuing my Ph.D., I worked as a full-time software engineer at Alibaba, where I gained valuable industry experience that complements my academic work.

Looking for Opportunities

I am actively seeking a faculty position or a postdoctoral research position in the areas of software engineering.
If you are interested in collaborating or have opportunities, please feel free to contact me via email.
