I do not take PhD students directly. Instead, as is typical in the United States, you will apply to Northwestern’s PhD program and be evaluated by the admissions committee. Upon admittance, you will take general courses and you will need to pass your preliminary exams in algebra, analysis, and geometry/topology.

In order to work with me specifically, you will typically need to take at least one course of mine and at least one independent study with me. This completed, you will need to pass the qualifying exam under my direction. (See the graduate handbook.) At this point it is technically possible for you to become my PhD student. I am always open to advising PhD students who have followed the steps above, but, even then, there are more students who want to work with me than I can accept.
