Zeyang Ma

 ABOUT ME

I am a Ph.D. candidate in Computer Science at Concordia University, supervised by Dr. Tse-Hsun (Peter) Chen. My research focuses on software engineering, mining software repositories, and software maintenance, with a particular interest in using large language models to improve log analysis and developer support.
