# Applied and Computational Mathematics

**Applied and Computational Mathematics at UW-Madison**

Welcome to the Applied and Computational Mathematics Group at the University of Wisconsin, Madison. Our faculty members, postdoctoral fellows, and students are involved in a variety of research projects, including fluid dynamics, partial and stochastic differential equations, scientific computing, biology, biochemistry, and topology.

To pursue graduate studies in Applied and Computational Mathematics, see the Mathematics Graduate Program.
