Algebra and Combinatorics »
Hopf algebras, coxeter groups, number theory, algebraic combinatorics, algebraic geometry, complexity theory, graded groups, and cohomology of rings. Applications include computer graphics, coding, and cryptography. There are significant overlaps with the research groups in number theory, geometry, and groups and dynamics.

Applied Mathematics and Interdisciplinary Research »
Many of our faculty conduct research with applications to other areas of science and engineering. Applied and interdisciplinary research overlaps with nearly every other research group in the department. These activities include computational materials science, porous media, fluid mechanics, transport equations, inverse problems and imaging, complexity theory, computational algebra, computational geometry, and mathematical biology. The applied mathematics faculty play key roles in two major university interdisciplinary institutes: the Institute for Applied Mathematics and Computational Science and the Institute of Scientific Computation.
