The Algebra Group at QMUL has a long and distinguished history, going back to such names as Kurt Hirsch, Karl Gruenberg and Ian G. Macdonald. Having made its reputation primarily in group theory, it now covers a wide range of areas of finite and infinite group theory, representation theory and related combinatorics, computational methods including algorithm design and database construction, as well as applications in combinatorics, statistics and physics.

Please consult the People section for more detailed information on Algebra Group faculty members and their research.
Seminars
We normally hold our Algebra Seminar on Mondays at 4.30pm. We aim for this seminar to be informal and accessible.
In conjunction with Imperial College and City University we run the weekly London Algebra Colloquium, which has been running continuously since 1950. We shall be hosting this Colloquium in Winter 2017, during which time our Algebra Seminar is suspended.
News
 Madhusudan Manjunath has been awarded a Leibniz Fellowship to visit Oberwolfach from January to March 2017.
 Algebra group members Matt Fayers and Alex Fink, together with Thomas Prellberg and Mark Walters, are organisers of the 2017 International Conference on Formal Power Series and Algebraic Combinatorics here at QMUL. Alex was on the programme committee for FPSAC 2015.
 Alex Fink was awarded EPSRC grant EP/M01245X/1 with value £100,118 for the research project Algebra and Geometry of Matroids, taking place 01/07/2015 to 31/12/2016.
 Leonard Soicher is part of the EPSRCfunded CoDiMa project EP/M022641/1, a Collaborative Computational Project running from 01/03/2015 to 29/02/2020, to support the development and use of the opensource GAP and SAGE mathematics systems.
Main areas of research
 finite simple groups, their structure and representations;
 representations of symmetric groups and Hecke algebras;
 growth functions on finitelygenerated groups, their combinatorics and numbertheoretic properties;
 computational group theory, development of algorithms and databases;
 algebraic combinatorics, matroids and tropical geometry;
