The Ph.D. program requires three letters of recommendation. We highly encourage at least one recommendation from an academic source, such as a current or former professor. A recommendation from a current or former supervisor who can comment on your professional background is also a good option.
GRE scores within 5 years of your application are required. However, if GRE results are pending you may submit your application if everything else is complete. GRE scores should be forwarded when available, so that a final decision can be made about your application.
