Graduate Studies

At the graduate level, studies in combinatorics may be undertaken which lead to both the M.Sc. and Ph.D. Details of our department's graduate programs can be reviewed here.

The School of Graduate Studies has a very helpful website about Memorial University, St. John's, and all that we have to offer.

We are always seeking interested and qualified candidates for our graduate programs, in which you can apply online.


During the Fall and Winter semesters we have a seminar that usually meets every week. Follow this link to view a list of scheduled talks.


Many of the following journals are available, either electronically or in hardcopy format at the Queen Elizabeth II Library.

Links to additional combinatorics journals can be found here.
