Hello! I am Sahar Kokaly

I am a Researcher at General Motors and a Research Assistant and PhD Candidate in the Department of Computing and Software at McMaster University . I am co-supervised by Tom Maibaum (McMaster Centre for Software Certification) and Marsha Chechik (University of Toronto). .

Previously, I was a Research Engineer on NECSIS (Network for the Engineering of Complex Software Intensive Systems), a joint collaboration between IBM, GM, Malina Software and numerous Canadian universities. I am also a former IBMer and an advocate for increasing female participation in STEM.

Research

My current research is broadly in the areas of Model-Driven Engineering and Safety Assurance. I focus on the topics of model management, megamodeling, and applications of model driven engineering in industry, most recently in the context of ISO 26262 automotive system safety compliance.
