Welcome to the Department of Mathematics

Welcome to the homepage of the UC Santa Barbara Mathematics Department.  We hope that this website provides you with the information you need and conveys some of the many interesting and exciting activities going on around the department.

The Department of Mathematics serves the UCSB campus by providing service courses for students taking mathematics as a requirement for a non-math major, a full list of upper division courses for our math majors and a wide variety of graduate courses that bring our graduate students closer and closer to the cutting edge research of our top-notch permanent faculty who have received numerous honors and awards.

To give you a sense of scale, the Mathematics Department has more than three dozen faculty members working in subfields that cover a broad spectrum of modern mathematics, half-a-dozen visiting assistant professors, more than 60 graduate students and over 1,300 math majors and pre-majors.

With that, I invite you to browse our website and learn more about the department.  Please feel free to contact us if you have any questions.

Stephen Bigelow
Professor and Chair


Michael Crandall, professor emeritus of mathematics at UCSB, was among 143 individuals elected to the National Academy of Sciences in 2023
“in recognition of their distinguished and continuing achievements in original research.”  Further details are in the press release.

Congratulations to Mathematics graduate student Fabio Ricci, who won the People's Choice Award for the 2023 Grad Slam Showcase!  This is an annual contest in which students communicate their research to a general audience in a three-minute talk. Fabio's talk was titled "Optimal Transport and Isoperimetric Inequalities (and why are pizzas usually round?)."
