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.

An international team of mathematicians, led by UCSB Professor Björn Birnir, has published a complete mathematical description of boundary layer turbulence. The paper, published in the journal Physical Review Research, synthesizes decades of work on the topic to provide a mathematical formula describing the turbulance caused when flow of water, air, or other fluids interacts with a boundary such as a pipe wall or the surface of the earth. Boundary layer interactions are important to many scientific and engineering fields, from meteorology to optimizing the aerodynamics of cars and aircraft.
