The Mathematics Department at the University of Surrey has one of the largest groups in the United Kingdom working on nonlinear mathematics and its applications.

The research interests of the Department cut a broad swathe through both pure and applied aspects of this area, ranging from ergodic theory, symplectic geometry and mathematical physics including gauge and string theories to novel applications in electronics, meteorology, neurobiology, arterial flow, molecular motors and spacecraft dynamics. A particular emphasis is placed on research at the interface between pure and applied mathematics. Research in the Department is organised into a number of Research Groups, but there are many overlaps and links between these:
