Trosolwyg
Rwy'n Gydymaith Ymchwil Ôl-ddoethurol sy'n gweithio ar hyn o bryd gyda'r Athro Peter Kille (Prifysgol Caerdydd), yr Athro David Spurgeon (UKCEH), Dr Stephen Lofts (UKCEH) a Dr. Stephen Short (UKCEH) ar effeithiau gwenwyndra metel ar infertebratau, gan ganolbwyntio ar ddull rhyngddisgyblaethol sy'n cyfuno dulliau meteleg, trawsgrifigol, ac ecotoccolegol.
Dechreuais fy ngyrfa yn gweithio ar yr ymateb straen mewn planhigion - fe wnes i Flwyddyn mewn Hyfforddiant Proffesiynol gyda'r Athro Hilary Rogers (Prifysgol Caerdydd) yn edrych ar effeithiau storio oer ar arogl mefus wedi'u torri'n ffres yn ystod fy ngradd (BSc Biocemeg). Es ymlaen i wneud PhD gyda'r Athro Hilary Rogers yn ymchwilio i agor lilïau a gwella datblygiad mewn blodau a ddewiswyd yn fasnachol, gan ddefnyddio technegau genetig, ffisiolegol a biocemegol.
Rwy'n angerddol am wyddoniaeth amaethyddol ac amgylcheddol ac yn anelu at barhau i weithio ar ddeall sail genetig ymatebion a datblygiad straen trwy ddulliau rhyngddisgyblaethol.

Ymchwil
Gwyddoniaeth planhigion
Mae gen i ddiddordeb mawr mewn gwyddor planhigion cymhwysol, yn benodol gan edrych ar ddatblygiad a senescence mewn cynnyrch ffres. Mae gen i dros 5 mlynedd o brofiad yn gweithio yn y maes hwn ac mae gen i brofiad o ddefnyddio dulliau cemeg ddadansoddol (Gas chromatography-time of flight mass spectrometry (GC-MS), biocemegol, a dulliau trawsgrifigol (dilyniannu RNA, qPCR) i ymchwilio i'r newidiadau genetig a ffisiolegol sy'n sail i brosesau biolegol.
Gwyddor yr amgylchedd
Angerdd arall i mi yw gwyddor amgylcheddol (llygredd metel), lle rwyf wedi bod yn gweithio ers bron i ddwy flynedd. Rwy'n defnyddio dulliau sbectrometrig fel sbectrosgopeg allyriadau optegol plasma wedi'i gyplysu'n anwythol (ICP-OES), a microdissection dal laser i ddadansoddi rhannu metel ar draws meinweoedd infertebratau a adrannau cellog a nodi mecanweithiau y tu ôl iddo.
'Dulliau omeg
Mae fy ymchwil wedi defnyddio sawl math o ddulliau 'omics, o drawsgrifigau, i ddadansoddi metabolomeg a chyfansoddyn organig anweddol (VOC). Mae'r rhain yn cael eu nodweddu gan brosesu a dadansoddi data mawr i dynnu tueddiadau a chydrannau diddorol allan gan ddefnyddio dulliau ystadegol cymhleth.
