The Topology and Algebra Group consists of Scott Andrews, Jens Harlander, Uwe Kaiser, Zach Teitler.
Research interests
Scott Andrews’s interests are in the representation theory of finite groups. He is particularly interested in matrix groups over finite fields and how their representation theory relates to the ring of symmetric functions and other combinatorial objects.
Jens Harlander’s interests are combinatorial topology and geometric group theory, with applications in 2- and 3-dimensional CW-complexes and manifolds. He is presently working on Whitehead’s asphericity conjecture, and on geometric realization problems, such as the Eilenberg–Ganea conjecture.
Uwe Kaiser’s interests are the topology of manifolds, including embeddings, immersions and singularities of maps; in particular 3-dimensional topology: theory of knots and links, quantum topology; related homotopy theory and algebra. He is presently working on topological quantum field theories and categorification.
Zach Teitler’s interests include a range of problems in the areas of algebraic geometry and commutative algebra, usually with a combinatorial or computational flavor, including: arrangements (of hyperplanes, points, etc); multiplier ideals (computation, applications to commutative algebra); secant varieties, computing rank, and Hilbert functions; and computer experimentation in mathematics.
Seminars
Members of the topology and geometry group organize two seminars, including the Topology Seminar and (together with members of the Cryptology Group the Algebra, Geometry, Cryptology Seminar. Students are welcome to participate in these activities.

Conference organizing
Jens Harlander and F. Rudolf Beyl organized the International Seminar on Low-Dimensional Homotopy Theory and Combinatorial Group Theory at the Wallowa Lake Lodge in Joseph, Oregon, in 2009.
Uwe Kaiser has organized Special Sessions at several recent regional AMS meetings, e.g. in 2006 a meeting on Floer homology and applications in Salt Lake City/UT (joint with Alexander Felshtyn), and in 2005 on the Algebraic Topology of Representation Varieties in Eugene/OR. He also organized a Special Session at the International AMS conference in Mainz and several International Topology Conferences in Germany. The geometric topology group also hosts the Cascade Topology Seminar about every third year.
Zach Teitler has additionally organized several regional meetings and conference sessions.
