Bywgraffiad
Hanes Byr
Ymgymerais â'm gradd BSc (Anrh) mewn Bioleg Gymhwysol ym Mhrifysgol Nottingham Trent yn arbenigo mewn bioleg planhigion a diogelu cnydau. Ar ôl graddio ym 1991, dechreuais fy ngyrfa ymchwil ym Mhrifysgol Nottingham gyda PhD a ariennir gan y BBSRC (1991-1995) ar y rhyngweithio rhwng rhizobia a'r Parasponia andersonii nad yw'n codlysiau (gyda'r Athro Ted Cocking a Dr Mike Davey). Ym 1995, arweiniodd y gwaith at swydd ôl-ddoethurol gydweithredol a ariennir gan DANIDA, rhwng y Laboratoire de Biologie Moléculaire, INRA-CNRS, Castanet-Tolosan, Ffrainc a Phrifysgol Nottingham (gyda'r Profs. Jean Dénarié a Ted Cocking). Y prosiect oedd astudio'r cysylltiad rhwng micro-organebau diazotroffig a phlanhigion cnydau nad ydynt yn codlysiau ar gyfer gosodiad N biolegol endophytig.
Yna symudais i Brifysgol Aberdeen ym 1998, lle canolbwyntiodd fy niddordeddau ymchwil ar ecoleg ficrobaidd ar brosiect NERC EDGE gyda'r Athro Jim Prosser ac mewn cydweithrediad â'r Athro Martin Embley, Amgueddfa Hanes Naturiol. Defnyddiwyd technegau 16S sy'n seiliedig ar rRNA i nodweddu amrywiaeth a strwythur cymunedol poblogaethau naturiol o facteria nitrifying mewn priddoedd glaswelltir ucheldir. Edrychodd y gwaith ar effeithiau gwahanol ffactorau amgylcheddol a chyfundrefnau rheoli ar amrywiaeth rhywogaethau, amrywiaeth genynnau swyddogaethol a gweithgaredd nitrification bacteria ocsideiddio amonia.
Yn 2001, cyrhaeddais Brifysgol Caerdydd i weithio gyda'r Profs. Andrew Weightman a John Fry ar brosiect a ariennir gan NERC MFMB i edrych ar gymunedau microbaidd yn y biosffer dwfn o lawr y môr, ac yna yn ddiweddarach gyda'r Athro John Parkes (Ysgol y Gwyddorau'r Ddaear a'r Amgylchedd). Roedd hyn yn cynnwys ymchwil ar brosiectau HERMES a NERC yr UE i edrych ar amrywiaeth cymunedau procaryotig mewn mannau poeth morol fel treiddiadau oer, twmpathau cwrel dŵr oer ac amgylcheddau anocsig eraill. Mae'r systemau pwysig hyn angen astudiaeth frys oherwydd eu bregusrwydd biolegol posibl, adnoddau genetig unigryw, perthnasedd byd-eang i gylchu carbon a sensitifrwydd i newid byd-eang ac effaith ddynol.
Ers 2017, mae fy niddordebau ymchwil yn cynnwys darganfod gwrthfiotigau o rywogaethau Burkholderia gyda'r Athro Eshwar Mahenthiralingam. Mae hyn wedi cynnwys nifer o brosiectau a ariennir gan LSBF Llywodraeth Cymru a BBSRC i ymchwilio i'r metabolion arbenigol a gynhyrchir gan rywogaethau Burkholderia ar gyfer gwrthfiotigau newydd ac asiantau rheoli biolegol, gan gynnwys diogelu planhigion rhag clefydau llambio. Rwyf hefyd wedi gweithio ar brosiect gyda'r Athro Andrew Weightman ar ddeall y cymunedau microbaidd sy'n gyfrifol am gael gwared biolegol ar gyfansoddion blas ac arogl (geosmin a MIB) yng ngwaith trin dŵr Dŵr Cymru. Cynhaliwyd yr ymchwil hon ochr yn ochr â gwaith ar brosiect Dadansoddi a Gwyliadwriaeth Dŵr Gwastraff Amgylcheddol Cymru ar gyfer Iechyd (WEWASH) a sefydlwyd i fonitro lefelau COVID-19 mewn dŵr gwastraff ledled Cymru. Roedd prosiect WEWASH yn gydweithrediad rhwng Prifysgol Caerdydd, Prifysgol Bangor, Iechyd Cyhoeddus Cymru a Dŵr Cymru Welsh Water. Defnyddiwyd y seilwaith a sefydlwyd yn ystod y prosiect hwn wedyn i helpu gyda materion eraill, megis y broblem sy'n dod i'r amlwg o ymwrthedd gwrthficrobaidd (AMR).
Ar hyn o bryd (ers 2024), rwy'n gweithio ar brosiect ALMOND a ariennir gan BBSRC ar ddatblygu celloedd artiffisial ar gyfer cyflenwi metabolion Burkholderia ar gyfer diogelu cnydau.
