Trosolwyg
Nid yw DNA mewn celloedd yn gweithredu fel helics dwbl noeth ond mae'n rhwym i wahanol broteinau strwythurol i ffurfio cromatotin. Mae modiwleiddio strwythur cromatin yn broses allweddol ym maes catalysis a rheoleiddio trawsgrifio genynnau, dyblygu DNA ac atgyweirio DNA. Rwy'n defnyddio technegau dilyniannu cromatotin cenhedlaeth nesaf i ddadansoddi swyddogaeth cromatotin mewn amrywiaeth o organebau gan gynnwys bodau dynol, planhigion, pryfed, burum ac archaea. Nod fy ymchwil yw deall bioleg cromatotin sylfaenol sy'n berthnasol i iechyd dynol, gwella cnydau ac esblygiad strwythur genom. Mae fy nghyllid diweddaraf wedi dod o'r BBSRC.

Bywgraffiad
Derbyniais BSc. (Anrh) o Brifysgol East Anglia ym 1989, D.Phil o Brifysgol Rhydychen yn 1994, a daeth yn Gymrawd yr Academi Addysg Uwch yn 2008.
Yn ystod fy ngwaith doethurol yn labordy Jane Mellor yn Rhydychen, cefais ddiddordeb mewn sut mae pecynnu ffisegol DNA yn dylanwadu ar fynegiant genynnau, a datblygu technoleg ar gyfer treulio cromatotin burum gyda niwcleasau er mwyn mapio strwythur cromatotin sy'n dal i gael ei ddefnyddio'n eang heddiw (Kent et al., 1993; Kent and Mellor, 1995). O 1994, ymgymerais â gwaith ôl-ddoethurol yn Rhydychen yn yr Adran Biocemeg (labordy Mellor) ac Ysgol Patholeg Syr William Dunn (labordy Proudfoot), a deuthum yn Ddarlithydd Adrannol yn yr Uned Geneteg yn 2002. Yn ystod y cyfnod hwn yn Rhydychen, gweithiais ar gyfadeiladau cyd-activator/repressor sy'n defnyddio ynni o ATP hydrolysis i ailfodelu strwythur cromatin, a chwaraeodd ran allweddol wrth ddarganfod swyddogaethau cellog dosbarthiadau ISWI a CHD yr ensymau hyn (Kent et al., 2001; Alen et al., 2002, Morillion et al., 2003, Martinez-Campa et al., 2004).
Yn 2006, cymerais Ddarlithyddiaeth ym Mhrifysgol Caerdydd ac ers hynny rwyf wedi cyhoeddi papurau: sy'n nodweddu amgylcheddau cromatin yn y locus rDNA a'r telomeres (Jones et al., 2007; Loney et al., 2009; torri rôl y dosbarth SWI / SNF ATPase RSC mewn ailfodelu cromatotin-yn ystod ffurfio a thrwsio egwyl cromosomau (Kent et al., 2007; Chambers et al., 2012a); nodi rôl ar gyfer ATPase dosbarth INO80 mewn swyddogaeth centromere a sefydlogrwydd genom (Chambers et al., 2012b). Prif ffocws fy labordy bellach yw datblygu technegau cromatotin-SEQ i ddadansoddi strwythur cromatotin a swyddogaeth ar lefel genom gyfan (Kent et al., 2011; Durand-Dubief et al., 2012; Platt et al., 2013; Platt et al, 2017). Rwyf wedi parhau i archwilio ailfodelu cromatotin mewn systemau organeb enghreifftiol fel burum ymholltiad ac Arabidopsis (Gal et al., 2015; Pass et al., 2017) a hefyd celloedd dynol (Harwood et al., 2019). Chwaraeais ran hefyd wrth ddarganfod y pensaernïaeth "supernucleosome" gleiniau newydd y gwyddys eu bod bellach yn bresennol mewn celloedd archaeolegol (Maruyama et al., 2013; Ofer, S. et al., 2023).
