Trosolwyg
Mae fy niddordebau mathemateg mewn algebrâu gweithredyddion - yn arbennig, theory is-ffactorau, y dechreuwyd gan fedalydd Fields, Vaughan Jones. Mae is-ffactorau yn gyffredinoliaeth o grwpiau sy’n cynnwys dimensiynau sydd ddim yn gyfanrifau. Maent yn amgodio cymesureddau cwantwm tu hwnt i grwpiau ac mae ganddyn nhw gymwysiadau yn Theori Maes Cydffurfiol (Conformal Field Theory, CFT). Rwyf wedi ehangu’r theory o is-ffactorau trwy luniadau perthnasol i grwpiau Lie. Mae fy ngwaith wedi darparu enghreifftiau newydd ar gyfer algebryddion, a oedd yn rhan o raglen 6-mis yn Sefydliad Isaac Newton, Caergrawnt, yn 2017.
Mae fy ymchwil presennol yn canolbwyntio ar ddosbarthu categorïau modiwl ar gyfer categorïau tensor modwlar sy’n ymddangos o fewn CFT, yn arbennig y rhai sy’n gysylltiedig i grwpiau Lie cryno, ond nid yn angenrheidiol yn gysylltiedig. Dechreuodd hyn gyda’r achos o SU(3) fel rhan o fy PhD, ond mae wedi ymestyn ers hynny i G2, Sp(2) ac SO(3).
Mae hefyd gennyf ddiddordebau mewn ymchwil addysg mathemateg, lle mae fy niddordebau yn bennaf yn ymwneud ag ymrwymiad myfyrwyr gyda'u astudiaethau. Mae agweddau arbennig o hyn yn cynnyws: agweddau ac ymarferion addysgu effeithiol, yn arbennig ar gyfer garfannau mawr; cymhellu ymrwymiad, yn arbennig trwy defnyddio asesiadau; a chyfeiriad meddwl ac agweddau at addysgu myfyrwyr.

Ymchwil
Mathematics Research
Most of my mathematics research has revolved around the theory of modular invariant partition functions for integrable statistical mechanical models associated to Lie groups and related constructions of braided subfactors or modular tensor categories. My early research focused on braided subfactors associated to the SU(3) modular invariants, although more recently I have focused on modular invariants for other rank two Lie groups, namely Sp(2), SO(5) and G2, and also non-connected groups such as the rank one Lie group SO(3). This has led to the classification of module categories for the modular tensor categories associated with SU(3) and, more recently, SO(3).
In particular, I have studied various invariants associated with these braided subfactors. This includes the computation of cell systems for the representation graphs (also called nimreps) which label the modular invariants, and the realisation of modular invariants by braided subfactors. I have studied spectral measures for the nimrep graphs. And in another direction I have constructed the higher preprojective algebras or corresponding Jacobi algebras associated to these nimreps, including certain homological invariants of these algebras.
Mathematics Education Research
I have been interested in mathematics education for a long time. More recently my interests have converged and crystallised around the idea of student engagement, specifically students' academic engagement with their mathematics studies at HE.
There are many relevant facets to this overarching theme:
- Approaches to teaching, particularly in large cohorts
- Incentivising engagement, particularly through use of assessment
- Assessment and Feedback, more generally, in supporting learning and engagement
- Learning communities
- Students' mindsets and approaches to learning
Some particular research interests going forward:
- Which forms of engagement are most effective for learning mathematics?
- What factors influence student engagement in mathematics?
- How to improve student engagement most effectively for learning?
- Is incentivised engagement effective for learning?
