The Mathematics Department at the University of Oregon offers a PhD in a variety of areas of mathematics. The American Mathematical Society has ranked us in the top group of U.S. research departments. The department has distinguished research groups in algebra, analysis, topology, geometry, probability, number theory, and mathematical biology. We are large enough to provide the quality and breadth required for a major research department, yet small enough so that graduate students have close interactions with the faculty. There are about 30 faculty members and 65 graduate students.
