Research

My research concerns the design and development of novel information systems based on social computing. My dissertation, Encouraging Expert Participation in Online Communities, investigates incentive mechanism designs and recommendation architectures for identifying expertise and eliciting human participation in online communities. I have experience in the evaluation of information trustworthiness and its application to complex systems. I am particularly interested in understanding and influencing the behavior of people in online communities. My work has been applied to several domains, including the prediction of improvised explosive device attacks, maritime domain awareness, and information security.

Current Research Questions:
  1. How can an incentive mechanism be designed such that a population of greedy agents produces beneficial system-wide properties in a question and answer system?
  2. Does such an incentive mechanism encourage human participation in a question and answer system?
  3. Does a question and answer system built upon the incentive mechanism encourage the participation of more highly qualified users, or experts?
  4. Does a question and answer system built upon the incentive mechanism foster satisfaction in its users?
