The Department of Mathematics at Oregon State University is a vibrant center for undergraduate and graduate-level mathematics. It is home to nearly 25 tenured and tenure-track faculty who are engaged in interdisciplinary and fundamental research in theoretical and applied mathematics, including but are not limited to mathematical modeling in the geosciences, mathematical biology, partial differential equations, geometry, number theory, numerical analysis, probability theory and mathematics education.

The graduate program has approximately 70 students from all over the world who are pursuing research and teaching under the direction of dedicated faculty advisors and mentors. The undergraduate program in mathematics includes: a comprehensive major with four different options in Applied & Computational Mathematics, Mathematical Biology, Statistics, and Secondary Teaching; a minor in actuarial mathematics; and a mathematics minor for non-majors.

The department is home to distinguished mathematicians who have received national and global honors for research and innovative teaching. Faculty, graduate and undergraduate students are involved in research grants and a variety of outreach and National Science Foundation-funded STEM (science, technology, engineering and mathematics) programs to enhance mathematical knowledge and teaching in the community and in Oregon schools.
