Steve Marsh is a Research Officer at in the National Research Council's Institute for Information Technology (NRC-IIT), an adjunct professor in Computer Science at UNB Fredericton, and an Adjunct Research Professor in Interdisciplinary Studies at Carleton University, Ottawa. He is the Research Lead for IIT's Privacy, Security and Trust initiative. He has been at NRC-IIT for 10 years, and in that time has worked on trust, distributed agent information systems (inventing the ACORN architecture), and computer supported collaborative work.

His PhD, finished in 1994 at the University of Stirling, in Scotland, introduced the world's first computationally tractable formalisation of the phenomenon of 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 sociaties.

His research interests include trust (in general, and also in specific areas such as trustable and trusting agents and computers), HCI, socially adept technologies, artificial life, Multi Agent Systems, social computers, complex adaptive systems, and critical infrastructure interdependencies, advanced collaborative environments, and enabling technologies to support ordinary people trying to work and play together to accomplish extraordinary things. He has published in most of these areas and has over 30 pubications in refereed conferences, journals, and books, and has been an invited speaker on topics as diverse as collaboration between the Arts and the Sciences, Trust, and Multi-Agent Systems.
