Matthew Mitsui

Ph.D. Candidate, Rutgers University

Welcome!


I'm a Postdoctoral Associate in the School of Communication & Information at Rutgers University. My dissertation focused on adopting a holistic approach to interactive information retrieval experimentation, using graphical modeling. My research interests include:

  • User Search Behavior
  • Search Task Detection
  • Interactive Information Retrieval
