Mae fy niddordebau ymchwil cyfredol yn ymchwilio a datblygu canolfannau lliw allyrru ffoton sengl ar gyfer cymwysiadau cyfathrebu a synhwyro mewn lled-ddargludyddion cyfansawdd llydan bwlch band gyda galluoedd twf a phrosesu aeddfed fel nitride gallium.
Mae fy ngwaith blaenorol wedi canolbwyntio ar ddatblygu canolfannau lliw mewn diemwnt fel adnoddau technoleg cwantwm ffotonig fel allyrwyr cwantwm ffoton sengl a soled cyflwr solet ar gyfer gwybodaeth cwantwm. Roedd hyn yn cynnwys cyplysu canolfannau lliw Swydd Wag Nitrogen (NV) neu Swydd Silicon Wag (SiV) i strwythurau ffotonig fel pelydr ïon ffocws (FIB) melino lensys trochi solet i wella effeithlonrwydd casglu ffotonau (APL, APL, 97, 24, 241901, 2010), cyseinyddion microdisk modd oriel sibrwd ar gyfer optomecaneg ceudod (Optica, 3, 9, 963. 2016), a waveguides ysgrifenedig laser femtosecond i arwain a chasglu golau a allyrrir (Llythyrau Opteg, 43, 15, 3586 2018).

Bywgraffiad
Ar ôl cwblhau MSci mewn Mathemateg a Ffiseg ym Mhrifysgol Bryste, ymunais â'r Ganolfan Ffotoneg Cwantwm gyda'r Athro Jeremy O'Brien a John Rarity, gan gwblhau PhD ar "Strwythurau a Thechnegau Ffotonig ar gyfer Mesur Gwell Qubits Spin mewn Diamond". Wedi hynny deuthum yn Gymrawd Ôl-ddoethurol Uchel Llygaid yng ngrŵp yr Athro Paul Barclay yn y Sefydliad Gwyddoniaeth a Thechnoleg Cwantwm ym Mhrifysgol Calgary. Ymunodd â Phrifysgol Caerdydd yn 2018, gan weithio gyda'r Athro Anthony Bennett a'r Athro Diana Huffaker ac ennill cymrodoriaeth ôl-ddoethurol Sêr Cymru a ariennir gan Lywodraeth Cymru i gefnogi fy ngwaith ar allyrwyr cwantwm mewn lled-ddargludyddion llydanfyl.
Yn 2022, deuthum yn ddarlithydd yn yr Ysgol Peirianneg ym Mhrifysgol Caerdydd. Mae fy ymchwil yn canolbwyntio ar nano-ffotoneg, opteg cwantwm, a thechnolegau synhwyro cwantwm yn seiliedig ar ganolfannau lliw allyrru ffoton sengl mewn deunyddiau lled-ddargludyddion llydan bandgap fel nitride gallium, diemwnt a deunyddiau 2D.
