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.

Congratulations to our Associate Professor, Xin Zhou, who is a invited speaker for the 2022 International Congress of Mathematicians (ICM) at St. Petersburg, Russia.  The ICM is held every four years, equivalent to the Olympics for mathematics.
Prof. Zhou graduated from Stanford University under the supervision of Prof. Rick Schoen in 2013.  He joined UCSB after three years at MIT as a Moore Instructor.  Prof. Zhou has made significant contributions in minimal surfaces and variational problems.  His recent work has resolved the Multiplicity One conjecture in the min-max theory of minimal surfaces.  He has also established the existence theory of constant mean curvature surfaces and the existence theory of minimal surfaces with free boundary.   His other honors include the Alfred P. Sloan Research Fellowship and NSF Career Award.

The transmission of SARS-CoV-2 Coronavirus (COVID-19) is an important research subject for public health. It is now known that airflow plays a large role in transmitting Covid-19. Professor Björn Birnir, Director of the Center for Complex, Nonlinear and Data Science at the University of California at Santa Barbara (UCSB), studied how airflow transmits COVID-19 in confined spaces. He created a model that predicts transmission rates in any given public space. The results can be used to alter real-life spaces to reduce COVID-19 infection rates.
