Wahab Hamou-Lhadj
PhD (Ottawa Univ), ing. (OIQ)

I am a Professor of Computer and Software Engineering in the Department of Electrical and Computer Engineering at Gina Cody School of Engineering and Computer Science, Concordia University.

My research focuses on the opportunities at the intersection of Software Engineering and Data Analytics. I am particularly interested in approaches that harness the wealth of information in software traces and logs, process logs, code commits, etc. to support software development and operations, software evolution and analytics, anomaly detection, and operational intelligence tasks.

My research has an industrial focus. Over the years, I have led many research and development projects with various organizations including Ericsson, CAE, Ubisoft, Marivent, Opal-RT, and DRDC (Defence R&D Canada).

I am fortunate to work with a great team of talented students and professionals. Together, we evaluate and apply techniques from Software Development and Modeling, Big Data Analytics, Machine and Deep Learning, and Stochastic Processes. Several of our original tools have been successfully transferred to our collaborators from industry and government and are used by a large number of developers.

Conference Organization in 2020

I am (co-)organizing the following events. Consider participating.
