Background

Dr. Marsh is a Trust Scientist and a thought leader in the phenomenon of trust for computational systems. His PhD was a seminal work that introduced the first formalization of the phenomenon of trust (the concept of computational trust), and applied it to multi-agent systems. As a milestone in trust research, it brought together disparate disciplines and attempted to make sense of a vital phenomenon in human and artificial societies, and is still widely referenced today, being in the top tenth of one percent of Citeseerx's most cited articles in computer science. Dr. Marsh's current work builds extensively on this model, applying it to network security, critical infrastructure protection, and mobile-device security.

Prior to working at UOIT, Dr. Marsh worked for 16 years in Government of Canada research labs: NRC Canada from 1996 to 2009, and CRC Canada from 2009 to 2012. His research covered areas as diverse (and linked) as:

  • advanced collaborative environments
  • information flow
  • network secure management
  • people-oriented technologies
  • trust and comfort

Before that, he was a Lecturer (Assistant Professor) at the University of Stirling in Scotland. Dr. Marsh has also been a visiting scholar at the University of Glasgow and Northumbria University in the U.K.

Other appointments:

  • Canadian delegate to IFIP 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)

Education

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

Research and expertise

Research areas

  • computational trust
  • human-computer interactions
  • information flow
  • information security
  • social knowledge
  • soft security
  • trust management

Dr. Marsh is a computer scientist with extensive social science experience. His research is concerned with the adaptation and adoption of human social values and skills to advanced information and communication technologies. His current work is concerned with:

  • Computational trust: Formal models, standardization and application.
  • Infrastructure protection based on trust and comfort reasoning methodologies.
  • Mobile device security and device comfort.
  • Regret management, reputation and trust management systems, trust and distrust in security settings.
  • The application of social collective knowledge to information management, network and communications security, and critical infrastructure protection.
