    A Message to Prospective Students

    If you'd like to pursue a higher degree after your graduation and are interested in my research topics, please read about our application details here. It is not necessary to contact me as I am normally unable to respond to email messages about applications to our program. You may, however, state in your statement of purpose that you are interested in my research.

    Our basic requirements for adimission are:

  • A CS degree
  • Overall average above 70%, CS average above 75% (minimum admission standards for other systems),
    and
  • TOFEL above 80 (computer-based 237 or paper-based 580) or IELTS 6.5 for non-native speakers except for exempted universities.

    CS program requirements are here

    FGRS has a calculation on costs for graduate study in Regina. A recent posted figure for visa students was around $1964 per month for PhD students with student visa. However, most of students I chated with spend much less than that. The Housing Registry of the University of Regina Students' Union lists some houses for rent in areas around UoR. You can also find a very informatic introduction to new students at Chinese Students & Scholars Association if you can read Chinese,

    Please note that I do not have summer internship positions at this time. For UoR students, we have an NSERC USAR program. You will be paid for over $5000 for summer research.

    Wikipedia has a general description on Canadian PhD Programs.
