The Department of Mathematics at the University of Chicago is one of the most exciting places in the world to do mathematics. We have over 30 tenured and tenure-track faculty working in areas as various as combinatorics, algebraic geometry, number theory, pure and applied analysis, representation theory, probability, geometry, topology, dynamical systems, logic, and financial mathematics, along with a similar number of Dickson Instructors. The research environment in the department is very lively, with seminars meeting virtually every day of the week and a constant stream of visitors. In addition, the department hosts regular colloquia, and several annual lecture series, including the Adrian Albert Lectures in Algebra, the Zygmund-Calderón Lectures in Analysis, the Charles J. Amick Memorial Lectures in Applied Mathematics, the Unni Namboodiri Lectures in Geometry and Topology, and the newly established ZhengTong Chern-Weil Symposium in Mathematics

.

At the graduate level, the department has a large __Ph.D. program in Mathematics__, a __joint Math/CS Ph.D. program__, and an __M.S. in Financial Mathematics__. We offer our different __undergraduate programs of study__ (B.S. in Mathematics, B.A. in Mathematics, B.S in Applied Mathematics, B.S. with a specialization in Economics), a __Minor in Mathematics__, and we collaborate with the Departments of Computer Science and Statistics to offer a __B.S. in Computational and Applied Mathematics__. Typically, around 10% of graduating seniors in the College graduate with degrees in mathematics.

A number of outreach programs operate out of the Department, including programs aimed at 5th-12th grade students (the __Young Scholars Program__ and __Math Circles__), Chicago Public School teachers (the __SESAME Program__ and the Polk Brother Foundation Program), and undergraduates across the nation (the __University of Chicago Mathematics Research Experience__ and occasional summer schools

The Department was founded in 1892, in the same year as the University itself. For a history of the Department written by Saunders Mac Lane, please see Celebratio Mathematica
