I am an Assistant Professor at the Department of Electrical Engineering and Computer Science at York University. I work at the intersection of Software Engineering and Machine Learning. More specifically, my research work focuses on taking the advantages of ML techniques in data process, knowledge representation, classification, NLP, etc., to address challenging issues of software reliability practices. My research interests include software engineering, software reliability, program analysis, software testing, and machine learning. The tools and techniques developed in my research have already helped detect hundreds of true bugs.

Looking for hard-working students
I have several cool projects, and I am looking for hard-working students to drive them! Email me if you're interested in working with me. More details are here Opportunities.
