Symmetric functions and representation theoryColloquium talk at DePaul University, 31 May 2019. Slides for the talk. Quantum groups via finite dimensional algebrasTalk given at the Pure Maths Seminar, UNSW, Sydney on 10 April 2018. Here are the slides for the talk. One point of the talk was to explain why the Serre relations are superfluous in presentations of (q)Schur algebras previously obtained by the speaker and other authors. Canonical idempotents in multiplicityfree families of algebras
Talk at Representation Theory and Physics, Leeds 19 July 2016. Here are the slides for the talk. This is based on joint work with Aaron Lauve and George Seelinger; the preprint is posted on the arXiv. SchurWeyl duality and the free Lie algebra
SchurWeyl duality over finite fieldsDecomposing tensor products of irreducible representations of algebraic groups in positive characteristicSeminar talk at University of York, 2014 June 12. Here are the slides for the talk. This talk is a survey of recent joint work with Chris Bowman, Anne Henke, and Stuart Martin.
Cellularity of generalized qSchur algebrasGiven at the conference Cohomology in Lie Theory, University of Oxford, 2428 June 2013. This talk is about an elementary approach to generalized qSchur algebras via a simple defining presentation by generators and relations. It is mostly based on the preprint arXiv: 1012.5983. Here are the slides for the talk and here is a printable version of the slides. (Note: The preprint has been revised substantially, and as a result some of the information in the slides is now outdated.)
Rational Schur algebrasTalk at the Boulder AMS meeting, 13th April 2013. Here are the slides for the talk. This is based on joint work with Richard Dipper and Friederike Stoll.
