Hanes Byr
Ymgymerais â fy ngradd 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 legume (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 Athro Jean Dénarié a Ted Cocking). Roedd y prosiect i astudio'r cysylltiad rhwng micro-organebau diazotrophig a phlanhigion cnydau nad ydynt yn codlysiau ar gyfer gosodiad N biolegol endophytig.
Yna symudais i Brifysgol Aberdeen ym 1998, lle canolbwyntiodd fy niddordebau ymchwil ar ecoleg ficrobaidd ar brosiect NERC EDGE gyda'r Athro Jim Prosser ac mewn cydweithrediad â'r Athro Martin Embley, Amgueddfa Hanes Naturiol. Fe wnaethom ddefnyddio technegau 16S rRNA i nodweddu amrywiaeth a strwythur cymunedol poblogaethau naturiol bacteria nitreiddio mewn priddoedd glaswelltir ucheldirol. Edrychodd y gwaith ar effeithiau gwahanol ffactorau amgylcheddol a chyfundrefnau rheoli ar amrywiaeth rhywogaethau, amrywiaeth genynnau swyddogaethol a gweithgaredd nitreiddio bacteria amonia-ocsideiddio.
Yn 2001, cyrhaeddais Brifysgol Caerdydd i weithio gyda'r Athro Andrew Weightman a John Fry ar brosiect a ariennir gan NERC MFMB i edrych ar gymunedau microbaidd yn y biosffer dwfn o dan y môr, ac yna yn ddiweddarach gyda'r Athro John Parkes (Ysgol 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 trwythau oer, twmpathau cwrel dŵr oer ac amgylcheddau anocsig eraill. Mae'r systemau pwysig hyn angen astudio ar frys oherwydd eu bregusrwydd biolegol posibl, adnoddau genetig unigryw, perthnasedd byd-eang i gylchu carbon a dueddiad 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 BGLl Llywodraeth Cymru a BBSRC i ymchwilio i'r metabolitau arbenigol a gynhyrchir gan rywogaethau Burkholderia ar gyfer gwrthfiotigau newydd ac asiantau rheoli biolegol. Rwyf hefyd wedi bod yn gweithio ar brosiect gyda'r Athro Andrew Weightman ar ddeall y cymunedau microbaidd sy'n gyfrifol am gael gwared ar gyfansoddion blas ac arogleuon biolegol (geosmin a MIB) yng ngwaith trin dŵr Dŵr Cymru. Mae'r ymchwil hon ochr yn ochr â fy ngwaith ar brosiect Dadansoddi a Gwyliadwriaeth Dŵr Gwastraff Amgylcheddol Cymru (WEWASH) a sefydlwyd i fonitro lefelau COVID-19 mewn dŵr gwastraff ledled Cymru. Mae'r prosiect WEWASH yn gydweithrediad rhwng Prifysgol Caerdydd, Prifysgol Bangor, Iechyd Cyhoeddus Cymru a Dŵr Cymru Welsh Water. Rydym yn gobeithio y gall y seilwaith a sefydlwyd yn ystod y prosiect hwn nawr helpu gyda materion eraill, megis y broblem sy'n dod i'r amlwg o ymwrthedd gwrthficrobaidd (AMR). Yn ddiweddar (diwedd 2024) rwy'n gweithio ar brosiect ALMOND a ariennir gan y BBSRC ar ddatblygu celloedd artiffisial ar gyfer cyflwyno metabolitau Burkholderia ar gyfer amddiffyn cnydau..
