Research excellence is a prime objective of the Mathematics Department. Faculty members conduct research in a variety of areas in pure and applied mathematics. Grants from the federal and state government support many faculty members' research programs. These grants often include support for graduate students seeking Ph.D. or master degrees. The research areas in the Department of Mathematics may be loosely grouped into:

- Algebra
- Analysis
- Applied and Computational Mathematics
- Dynamical Systems and Ergodic Theory
- Geometry and Topology
