Trosolwg
Mae fy niddordebau mewn ymchwil gymhwysol, arloesol. Mae fy mhrosiect presennol yn ymchwilio i gael gwared biolegol o gyfansoddion blas ac arogl o ddŵr yfed. Ariennir y prosiect hwn gan UK Water Industry Research (UKWIR) ac mae'n cael ei gynnal ym Mhrifysgol Caerdydd o fewn grŵp ymchwil yr Athro Andrew Weightman mewn cydweithrediad â Stantec.
Yn flaenorol, rwyf wedi cael y fraint o gyfrannu at amrywiaeth o brosiectau diddorol gan gynnwys Dadansoddi a Gwyliadwriaeth Dŵr Gwastraff Amgylcheddol Cymru ar gyfer Iechyd (WEWASH), a oedd yn monitro lefelau SARS-CoV-2 mewn dŵr gwastraff yng Nghymru, gan gyfrannu at ymdrechion gwyliadwriaeth COVID-19 yng Nghymru a llywio mesurau'r Llywodraeth, a gweithio gyda Volac International Ltd. i ddatblygu eu gallu dadansoddi biowybodeg genom cyfan ar gyfer maeth anifeiliaid.
Roeddwn hefyd yn rhan o brosiect REMI-seq i gynhyrchu casgliad mawr o amrywiadau Dictyostelium fel adnodd cymunedol (a ariennir gan Ymddiriedolaeth Wellcome). Mae'r amoeba cymdeithasol, Dictyostelium, yn fodel addas ac economaidd yn enwedig ar gyfer astudio prosesau sy'n ymwneud ag iechyd dynol a chlefydau. Roedd fy ngwaith cynharach yn cynnwys y planhigyn model, Arabidopsis, a datblygu technegau ar gyfer cyflwyno amrywiad i enynnau unigol ar gyfer esblygiad wedi'i gyfeirio.
Rwy'n rhan o'r grŵp Microbiomau, Microbau a Gwybodeg (MMI).

Ymchwil
Rwy'n arbenigo mewn cynhyrchu a defnyddio casgliadau mawr o straen i ddarganfod y mecanweithiau y tu ôl i brosesau biolegol, yn y 'wet-lab' a thrwy wybodeg. Rwyf hefyd yn datblygu offer sy'n hwyluso eraill i gael mynediad at dechnolegau arbenigol.
Fel rhan o brosiect a ariennir gan Ymddiriedolaeth Wellcome, rwyf wedi cynhyrchu casgliad mawr o amrywiadau Dictyostelium fel adnodd cymunedol. Mae'r amoeba cymdeithasol, Dictyostelium, yn fodel addas ac economaidd yn arbennig ar gyfer astudio'r broses sy'n ymwneud ag iechyd dynol a chlefydau.
Yn flaenorol, rwyf wedi cynhyrchu a sgrinio casgliad mawr o amrywiadau Arabidopsis. Nodweddwyd un o'r amrywiadau ymhellach a dangoswyd ei fod yn elfen allweddol wrth wneud planhigion yn wydn i amodau garw fel sychder; Mae'r wybodaeth hon bellach yn cael ei defnyddio i astudio sut na fydd cynnyrch cnydau yn cael ei gyfaddawdu mewn hinsawdd annibynadwy.
Rwyf hefyd wedi datblygu technegau ar gyfer esblygiad cyfarwyddedig gan gynnwys TriNEx sy'n ddull ar gyfer cynhyrchu llyfrgelloedd mawr o amnewidiadau asid amino sengl ar gyfer proteinau sengl y gellir eu sgrinio in vivo.

Bywgraffiad
Enillais fy B.Sc. gradd mewn Gwyddorau Biolegol (Biocemeg) o Brifysgol Caerlŷr ac yna Ph.D. mewn Geneteg Moleciwlaidd Planhigion. Treuliais 2 flynedd fel Ysgolhaig Rhyngwladol yn yr Adran Gwyddorau Planhigion yn UCDavis.
Ymunais â Phrifysgol Caerdydd yn 2006 i ddatblygu technegau esblygiad uniongyrchol o fewn grŵp Dr Dafydd Jones. Ers hynny rwyf wedi gweithio i Ganolfan Ymchwil Gofal Lliniarol Marie Curie (MCPCRC) sydd wedi'i lleoli o fewn Uned Treialon Clinigol Cymru (WCTU), a Pharc Genetig Cymru fel Swyddog Ymgysylltu â'r Cyhoedd. Yn 2014 ymunais â grŵp Harwood yn Ysgol y Biowyddorau Caerdydd i gynhyrchu adnodd mutant genom eang ar gyfer genomeg swyddogaethol Dictyostelium (REMI-seq).
Ar hyn o bryd, rwy'n datblygu gallu dadansoddi biowybodeg genom cyfan ar gyfer maeth anifeiliaid. Mae hon yn bartneriaeth rhwng busnes llaeth rhyngwladol (Volac Int. Ltd.) a grŵp Microbiomau, Microbau a Gwybodeg (MMI) Prifysgol Caerdydd.
