Wahab Hamou-Lhadj, PhD, ing, SMIEEE Professor, ECE, Concordia Applied AI Institute, Concordia University Gina Cody Research and Innovation Fellow Affiliate Researcher, NASA JPL, Caltech
My current research focuses on helping organizations improve the quality and reliability of their software ecosystems and digital infrastructures using Artificial Intelligence and Software Observability. I am interested in both the technological and governance aspects of applied AI.
My work spans across the entire DevOps stack to meet the increasing demand for reliable digital systems in the era of AI systems, digital transformation, cloud intelligence, and advanced distributed architectures.
My team employs various techniques including machine learning, LLMs, AIOps, software observability and monitoring, tracing and logging, model-driven engineering, and empirical studies. See publication list.
I have long-standing partnerships with various companies, most notably Ericsson Global AI Accelerator (GAIA), and NASA JPL, where I currently hold the position of Affiliate Researcher.
I have taught and developed courses on machine learning, AI for IT Operations (AIOps), model-driven engineering, software development, product design using Scrum, BPM, and TOGAF. I am also the content developer of OMG certification programs OCUP2 (OMG Certified UML Professional) and OCEB2 (OMG-Certified BPM).
