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, the Patrick Billingsley Lecture in Probability (joint with the Statistics Department), 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
