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

I am a Professor 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 machine data (software traces and logs, machine-generated logs, code commits, etc.), using data analytics, machine and deep learning, and modeling techniques, to support software development and operations, software evolution and analytics, security monitoring, process analysis, 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 on the organization committees of ICSE 2019 and ICPC 2019 . Both conferences will be held in Montreal from May 25 to May 31. Consider attending!

I am currently an active governance board member of ITACS BTM Forum, a leader in digital transformation and disruptive technologies.

I was heavily involved in the development of OCUP2 (OMG Certified UML Professional) and OCEB2 (OMG-Certified Expert in BPM) certification programs, taken by thousands of practitioners every year.
