Assistant Professor

About Me

I am an Assistant Professor at the School of Information Technology, York University. I completed my Ph.D. at Concordia University in 2022, under the supervision of Dr. Tse-Hsun (Peter) Chen (Concordia University) and Dr. Weiyi (Ian) Shang (University of Waterloo). My research mainly focuses on software engineering, including AIOps, SE for AI, mining software repositories, and empirical software engineering.
