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. My industry experience includes large-scale software engineering at Alibaba Group and industry-applied research at Huawei Canada (2012 Laboratories).
My research focuses on software quality assurance, with an emphasis on the performance and reliability of complex software systems. I use program analysis, software analytics, computer vision, and large language and vision-language models to analyze, understand, and improve software systems at scale. My work has been published in leading venues including IEEE TSE, ACM TOSEM, ICSE-SEIP, ASE, and AAAI.
