Ontario Tech acknowledges the lands and people of the Mississaugas of Scugog Island First Nation.

We are thankful to be welcome on these lands in friendship. The lands we are situated on are covered by the Williams Treaties and are the traditional territory of the Mississaugas, a branch of the greater Anishinaabeg Nation, including Algonquin, Ojibway, Odawa and Pottawatomi. These lands remain home to many Indigenous nations and peoples.

We acknowledge this land out of respect for the Indigenous nations who have cared for Turtle Island, also called North America, from before the arrival of settler peoples until this day. Most importantly, we acknowledge that the history of these lands has been tainted by poor treatment and a lack of friendship with the First Nations who call them home.

This history is something we are all affected by because we are all treaty people in Canada. We all have a shared history to reflect on, and each of us is affected by this history in different ways. Our past defines our present, but if we move forward as friends and allies, then it does not have to define our future.

Stephen Marsh is a Professor and computational philosopher with extensive experience in the application of human social norms such as trust, forgiveness and wisdom to computational and information systems. He is the inventor of the concepts of Computational Trust and Device Comfort, and the co-originator of Slow Computing. He works primarily towards the empowerment of people through enabling socio-technical systems to enhance awareness, give advice, and provide encouragement. His work has been applied and published in areas as diverse as social psychology, information systems, HCI, CSCW, AI, Information Security and Mobile Device Awareness. 

Prior to being with Ontario Tech University, Steve worked within Canadian Government Laboratories (NRC and CRC) as a research scientist for 16 years, and before that he was a Lecturer in Computing Science at the University of Stirling from 1993-1996. He has been a visiting scholar at the University of Glasgow and Northumbria University in the UK, and a Mercator Fellow at Darmstadt Technical University. He has been an adjunct professor at Carleton University (Systems and Computer Engineering and Cognitive Science) and the University of New Brunswick (Computer Science) as well as Ontario Tech University (Business and Information Technology). 

Steve has supervised to successful completion PhD, Masters and Undergraduate projects in areas such as Human Computer Interaction, Trust Management, Intrusion Detection, Device Comfort, Privacy, Information Security and Multi-Agent Systems. He is the author or co-author of numerous conference, journal, and book chapters and the odd patent.

Steve is the Chair of IFIP Working Group 11.11 (Trust Management) and Canadian Delegate to IFIP Technical Committee 11 (Security and Privacy Protection in Information Processing Systems).

Other appointments:

  • Canadian delegate to International Federation for Information Processing Technical Committee 11: Security and Privacy Protection in Information Processing Systems.
  • Adjunct Professor at the University of New Brunswick (Computer Science).
  • Adjunct Professor at Carleton University, Ottawa (Systems and Computer Engineering and Cognitive Science).


  • BSc in Computing Science University of Stirling in Scotland 1990
  • PhD in Computing Science University of Stirling in Scotland 1994
