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 range of areas in group theory, representation theory, number theory, algebraic combinatorics, algebraic geometry, logic, homological/categorical algebra, and computational methods.

Faculty members in other groups whose research includes high levels of Algebra include Xin Li (GA), Shahn Majid (GA), and Hugo MaruriAguilar (PA).
Seminars
We normally hold our Algebra Seminar during term 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.
News
 We are pleased to announce that the newly appointed lecturers in number theory, Steve Lester and Abhishek Saha have joined the Algebra Group.
Steve is interested in analytic number theory, especially Lfunctions, multiplicative functions, classical automorphic forms, and mathematical physics, especially quantum chaos.
Abhishek is interested in classical and higher rank modular forms, automorphic representations and the Lfunctions attached to them.
 We are pleased to announce that Behrang Noohi and Ivan Tomašić have joined the Algebra Group.
Behrang is interested in higher categorical/derived structures in algebra and geometry. More specifically: algebraic/differentiable/topological stacks, moduli problems, higher dimensional groups and higher Lie theory, and string topology.
Ivan studies model theory and its applications in algebraic geometry and number theory. More specifically, his interests include difference algebra and geometry (relating to the arithmetic aspects of the Frobenius automorphism), measurable structures, (nonstandard) cohomology theories, and motivic integration.
Main areas of research
 group theory: structure of finite groups, growth functions on finitelygenerated groups and their combinatorics and numbertheoretic properties, computational group theory and grouptheoretical databases;
 representation theory: representations of finite groups, representations of symmetric groups and Hecke algebras;
 algebraic combinatorics: algebraic graph theory, matroids and tropical geometry, finite geometry, computation;
 number theory: Ktheory of number fields, analytic number theory, Lfunctions, multiplicative functions, classical automorphic forms, classical and higher rank modular forms, automorphic representations;
 homological algebra: higher categorical/derived structures in algebra and geometry;
 model theory and its applications in algebraic geometry and number theory;
 mathematical physics: exceptional groups and Lie algebras and applications to physics, quantum chaos.
