Perimeter Scholars International

Perimeter Scholars International (PSI) is a 10-month intensive coursework Master’s-level program that takes place from August to June each year at Perimeter Institute. The program is designed to expose outstanding students to the full spectrum of theoretical physics, taught by a stellar array of international lecturers and dedicated professional tutors. Students take all their courses at Perimeter Institute, and receive an MSc from the University of Waterloo upon graduation.

The unique and innovative Perimeter Scholars International is intended to bring highly qualified, highly motivated graduate students to the cutting edge of theoretical physics in an intense, interactive learning environment. The program provides a broad range of expertise and perspectives, with courses taught in three-week modules by Perimeter Institute faculty and other top visiting lecturers from around the world. Students not only experience all aspects of foundational theoretical physics, but also learn practical skills such as computer-based model development, independent thinking, and collaborative problem solving. In the latter part of the program, students defend original research theses, many of which are later accepted for publication. The program is run in partnership with the University of Waterloo, which confers a Master's degree on completion of the program.


The PSI program provides an exciting path for some of the world’s brightest young minds to follow. Many students come to the program for a variety of reasons. Some are attracted to the possibility of continuing on to a PhD with a Perimeter faculty member. Many students apply who have decided that they want to do theoretical physics but do not yet know enough to commit to a specific sub-area, such as string theory, particle physics or condensed matter. Studying a broad range of theoretical physics subjects with a diverse group of highly motivated students is a great way to discover what is right for you.


The PSI program is taught by many outstanding international lecturers, visiting to lecture for three weeks at a time, in combination with Perimeter Institute faculty members and dedicated postdoctoral tutors – PSI Fellows – who are present throughout the course. |  PSI Faculty  |  PSI Fellows  |


The PSI program aims to expose students to all areas of theoretical physics, with opportunities to delve more deeply into the research areas that excite them the most. Building on this scientific foundation, many graduate students continue their research in PhD programs with Perimeter faculty, and others have gone on to PhD programs at other institutions, including:

  • Columbia University
  • Caltech
  • Berkeley
  • Oxford
  • Princeton
