The major part of my research is analysing the micro and macro-behavioural phenomena in computational trust and reputation systems, in particular their causal relationship to user bias . In that regard, my research interests include:

  • Trust: socio-cognitive aspects, computational analogue of trust, its applicability and non-applicability in a virtual setting (“artificial trust”), contextual trust-reasoning;
  • Reputation systems: the impact of scale, context, dynamics, privacy, risk;
  • Cybernetic principles of trust systems design;
  • Trust as an emergent systemic property: micro-incentives (of the system entities) and macro-behaviour (of the system)
  • Information Fusion and Soft Computing
  • The compatibility and interchangeability between traditional and computational social networks’ premises and methodologies

The major sources for my thoughts:

  • History and Philosophy of Science
  • Principles of (self)sustainability
  • Complexity and Cybernetics
  • Probability Theory –  history, foundations and generalisations
  • Sociology and Network Theory
