Prospective graduate students: Graduate Study in IR at UT Austin
Current MSIS students

  • Consider a culminating capstone report (one-semester) or thesis (two semesters) in IR
  • Earn a coursework specialization in Information Retrieval or Crowdsourcing / Human Computation
Undergraduates: inquire regarding research opportunities or visit EUREKA!. Independent course credit is possible (e.g., in computer science). Undergraduates have co-authored research papers with us in the past. Also see the CNS page on Undergraduate Research.

High School Students: apply for UT's Summer Research Academy
