Mae fy niddordebau ymchwil yn canolbwyntio ar ddeall sut mae ymatebion imiwnedd addasol, sy'n cael eu gyrru gan gelloedd T, yn ymateb i heintiau firws a bacteria a hefyd sut mae micro-organebau pathogenig yn defnyddio strategaethau esblygol i osgoi celloedd T. Ar ben hynny, mae gen i ddiddordeb brwd mewn darganfod sut mae'r math hwn o imiwnedd cellog yn cael ei reoleiddio gan signalau biolegol (sytocinau) a sut y gall ansefydlogi pan fydd ymatebion imiwnedd byd-eang yn cael eu anghydbwyso, fel mewn sepsis.
Ar hyn o bryd rwy'n ymwneud â "Project Sepsis", cydweithrediad ymchwil ar draws disgyblaethau meddygaeth a gwyddonol sydd wedi'i sefydlu i fynd i'r afael ag angen meddygol brys am ddiagnosis cywir, cyflym sy'n canfod yr achos heintus sy'n sail i ddechrau sepsis. Yma, nod allweddol yw datgysylltu'r mecanweithiau imiwnolegol sy'n ysgogi atal imiwnedd addasol mewn sepsis gyda'r bwriad o helpu i wella diagnosis ac i lywio dyluniad ymyriadau therapiwtig newydd.

Bywgraffiad
Dechreuodd fy ngyrfa ymchwil yn 2004 gyda Ph.D. yn labordy yr Athro Martin Rowe a Dr Paul Brennan ym Mhrifysgol Caerdydd. Yn ystod y cyfnod hwn, canolbwyntiodd fy ymchwil ar ddyrannu sut mae Firws Epstein-Barr (EBV) yn rheoleiddio mecanweithiau gwrthfeirysol allweddol (signalau interferon) yn ystod trawsnewidiad celloedd-B. Sbardunodd yr ymchwil hon fy niddordeb mewn modiwleiddio cytokine imiwnedd addasol. O'r fan hon, ymgymerais â'm swydd ôl-ddoethurol gyntaf, dan oruchwyliaeth Dr Dipak Ramji ym Mhrifysgol Caerdydd, lle astudiais sut y mae cytocinau yn trin ffurfio celloedd ewyn sy'n deillio o facroffagau. Mae ffurfio celloedd ewyn yn broses allweddol ym pathogenesis atherosclerosis a chlefyd y galon a phenderfynais y gallai interleukin-33 (IL-33) atal ffurfio celloedd ewyn macrophage, a oedd yn ddarganfyddiad newydd ar y pryd.
Yn 2010, dyfarnwyd Cymrodoriaeth Gwerth Ymddiriedolaeth Wellcome mewn Pobl (VIP) i ymuno â labordy yr Athro David Price ym Mhrifysgol Caerdydd i ehangu fy niddordebau mewn imiwnoleg firaol a bioleg cytokine. Yma, canolbwyntiais ar berfformio dulliau uwch-dechnoleg (cytometreg llif polychromatig, dilyniant derbynnydd celloedd T uwch) i ddeall sut mae ymatebion imiwn celloedd T sy'n benodol i antigen-benodol yn cael eu defnyddio mewn bodau dynol a llygod yn ystod firws (HIV, cytomegalofirws, EBV, firws dengue), coloneiddio microbaidd, llid a chlefyd. Yn ystod y gymrodoriaeth hon a thu hwnt (2010-2018), rwyf wedi gwneud rhai cyfraniadau sylweddol i'r maes imiwnolegol, gan gynnwys nifer o gyhoeddiadau effaith uchel (Cell, Imiwnoleg Natur, Imiwnoleg Gwyddoniaeth, Imiwnedd, Journal of Experimental Medicine), ac rwyf wedi cael gwahoddiad i roi darlithoedd ar yr ymchwil hon mewn cynadleddau, cwmnïau biotechnoleg a sefydliadau academaidd yn y DU ac Awstralia. Yn ogystal, ehangais fy niddordebau mewn cytocinau (ee IL-33) trwy archwilio sut maent yn rheoleiddio imiwnedd celloedd T yn ystod haint firws yn vivo.
Yn 2018, cefais fy recriwtio fel Darlithydd mewn Imiwnedd Systemau ym Mhrifysgol Caerdydd i gymhwyso fy arbenigedd mewn proffilio celloedd T yn ystod yr haint ar gyfer "Project Sepsis", cydweithrediad ymchwil newydd a sefydlwyd i fynd i'r afael ag angen meddygol brys i roi diagnosis cywir o sepsis ac i ddatblygu ymyriadau therapiwtig newydd. Yn 2023, cefais fy nyrchafu i Uwch-ddarlithydd ac mae fy niddordebau ymchwil ar hyn o bryd yn canolbwyntio ar ddeall sut mae celloedd T yn ymateb i heintiau bacteriol a firaol a hefyd sut mae'r organebau mircro-organebau hyn yn defnyddio strategaethau i osgoi celloedd T
