Rwy'n astroffisegydd tonnau disgyrchol, ac rwy'n chwilio am dyllau du a sêr niwtron gan ddefnyddio tonnau disgyrchol i ddatgloi cyfrinachau sut mae hanfodion y bydysawd yn gweithredu. Arloeswyd y ffordd newydd hon o edrych ar y byd o'n cwmpas yn 2015, gyda chanfod y LIGO-Virgo Collaboration's o uniad twll du deuaidd GW150914.

Rwy'n aelod o Gydweithrediad Gwyddonol LIGO, ac yn arbenigo yn y dehongliad astroffisegol o arsylwadau tonnau disgyrchol. Mae fy ngwaith yn cynnwys swyno'r tyllau duon a sêr niwtron a ganfuwyd ar ffynhonnell y signalau, a chynllunio ar gyfer darganfyddiadau seryddiaeth tonnau disgyrchol dros dro yn y dyfodol.

Mae fy ffocws ymchwil mewn astroffiseg tonnau disgyrchol. Mae gen i ddiddordeb arbennig mewn:

Seryddiaeth: Arsylwadau tonnau disgyrchol dros dro. Yn benodol â'r rhwydwaith LIGO (Arsyllfa tonnau Disgyrchol Ymyriadurol Laser) a rhwydwaith interferometer Virgo ac ar y cyd â chymheiriaid Electromagnetig neu Neutrino.
Ffiseg arbrofol: Dylunio arbrofol optimized synwyryddion yn y dyfodol. Modelu cyfannol ar gyfer arsyllfeydd tonnau disgyrchol.
Astroffiseg: Deall ffynonellau disgyrchol gydag amcangyfrif paramedr gan ddefnyddio Dulliau Bayesaidd. Casgliad o eiddo cyffredinol gan ddefnyddio digwyddiadau lluosog.
