About

I am an associate professor at the School of Electrical Engineering and Computer Sciecnce -- University of Ottawa.

Prior to coming to Ottawa, I was a senior scientist (2012 - 2019) at the SnT Center -- University of Luxembourg and a scientist (2009 - 2012) at the Simula Research Laboratory. I received my M.Sc. and Ph.D. from the University of Toronto in 2003 and 2008, respectively.

Research Interests:

  • Software testing and verification
  • Search-based software engineering
  • Connected and autonomous systems
  • Applied artificial intelligence
  • Formal and empirical research methods

Students:

  • Jaekwon Lee (PhD)
  • Jia Li (PhD)
  • Baharin Aliashrafi (MSc)

Research:

My research interests are in software engineering, focusing on software verification and analysis of cyber physical systems and autonomous, connected and smart systems. In my research, I often draw on techniques from various disciplines, such as formal software and logical modeling, meta-heuristics optimization, machine learning, system and control engineering, and empirical methods.



In the past years, I have extensively worked on testing and fault localization of cyber physical systems and have applied my research to autonomous vehicles and IoT systems. Further, I have worked on the following topics related to requirements analysis, modelling, and design time analysis of CPS: requirements traceability and analysis, automated configuration of product line systems, designtime schedulability analysis, and simulation and modeling of CPS. I have, for the past ten years, been conducting my research in close collaboration with industry partners in telecommunication, maritime, energy, automotive and aerospace sectors.
