Trosolwyg
Rwy'n Ddarlithydd mewn Gwyddorau Mathemategol sy'n gweithio yn y grŵp ymchwil Geometreg, Algebra, Ffiseg Fathemategol a Thopoleg . Cyn cyrraedd Caerdydd, gweithiais ym Mhrifysgol Abertawe fel Cymrawd Daphne Jackson.
Mae fy ymchwil mewn geometreg, ar gyfer harddwch cynhenid y pwnc mathemategol pur ac ar gyfer ei gymwysiadau mewn gwyddor data yn ogystal ag mewn perthnasedd mathemategol. Mae meysydd penodol o ddiddordeb yn cynnwys crymedd , cymesuredd, cwymp cyfaint, dadansoddi data topolegol a chasgliad geometrig.
Cefnogir fy ngwaith gan Gymrodoriaeth Arweinwyr y Dyfodol UKRI.

Ymchwil
Diddordebau Ymchwil
- Geometreg Riemannian
- Geometreg alexandrov
- Mannau hyd Lorentzian
- Casgliad geometrig
Mae fy ngwaith presennol mewn geometreg Riemannian yn canolbwyntio ar ddeall manifolds o gyfaint isel a submetries. Mewn geometreg Alexandrov, rwy'n astudio sut mae cymesuredd a chrymedd yn rhyngweithio. Rwy'n cymhwyso fy ngwybodaeth o geometreg Alexandrov i theori newydd gofodau hyd Lorentzian, sydd fel spacetimes, ond yn llai rheolaidd. Mewn casgliadau geometrig rwy'n astudio dylanwad crymedd ar berfformiad estimator ac amcangyfrif meintiau geometrig.
