Matthew Mitsui

Ph.D. Candidate, Rutgers University


I'm a Ph.D. Candidate in the department of Computer Science at Rutgers University. I work at the Infoseeking Lab at the School of Communication and Information, currently researching user search behavior and query recommendation. My research interests include:

  • User search behavior
  • Collaborative Information Seeking
  • Simulations of User Behavior
