I lead the Software PErformance, Analysis, and Reliability (SPEAR) lab at Concordia University. My research focuses on improving the quality of large-scale software systems. Specifically, I work on areas such as log analysis and AIOps, software performance analysis, software testing, and mining software repositories. My research group has extensive collaboration with companies such as ERA Environmental, Ericsson, Microsoft, and BlackBerry.

The research tools developed by myself and my students were integrated into industrial practice for ensuring the quality of large-scale enterprise systems. My research has received multiple prestigious awards and I am ranked as one of the most active software engineering researchers around the world by an independent study published in JSS. Several graduated PhD/PostDoc from the SPEAR lab are now tenure-track assistant professors around the world (e.g., York University, University of Alberta, DePaul University, and IIT Gandhinagar).

In particular, my research aims to solve challenges such as:

• Can we leverage Large-Language Models (LLM) to assist developers with development, debugging, and maintenance?
• Can we quickly help developers debug production systems by utilizing rich software data?
• Can we provide suggestions on how to optimize the software system by analyzing user usage data?
• How to improve software quality assurances in DevOps environments by analyzing test results from continuous integration?
• Can we provide useful suggestions to developers by mining software development history?

To perspective graduate students: Concordia has a very strong research presence in Software Engineering. Concordia’s Software Engineering is currently ranked as the 5th in the world. Concordia is also ranked as one of the top 100 universities under 50 years old in the world . Montreal is the second largest city in Canada and is ranked as the best city for students in the world.
