Cydymaith Ymchwil, Is-adran Meddygaeth Seicolegol a Niwrowyddorau Clinigol
Trosolwyg
Mae fy ymchwil yn canolbwyntio ar ddatblygu a gwerthuso ymyriadau seicolegol ar gyfer anhwylderau sy'n gysylltiedig â thrawma. Gan weithio o fewn ffrwd waith Datblygiad Ymyriad y Ganolfan Genedlaethol ar gyfer Iechyd Meddwl (NCMH) mae gen i brofiad helaeth o weithio ochr yn ochr ag arbenigwyr trwy brofiad byw i ddatblygu ymyriadau newydd gan ddefnyddio dulliau cymysg o weithredu. Roedd fy PhD yn cynnwys datblygu a threialu profion Gwanwyn , rhaglen newydd wedi'i llywio ar y rhyngrwyd ar gyfer PTSD sydd bellach yn cael ei gweithredu yn y GIG. Ar hyn o bryd rwy'n gweithio ar ddatblygu ymyriadau tebyg ar gyfer Anhwylder Galar Hir, PTSD cymhleth a fersiwn bwrpasol o'r Gwanwyn ar gyfer cyn-filwyr milwrol. Rwyf wedi cynnal sawl adolygiad Cochrane ac wedi gweithio i'r Sefydliad Cenedlaethol dros Ragoriaeth mewn Iechyd a Gofal (NICE) i gynhyrchu canllawiau Ymarfer Clinigol. Roeddwn yn aelod o bwyllgor canllawiau triniaeth y Gymdeithas Ryngwladol Astudiaethau Straen Trawmatig (ISTSS), gan arwain at gyfosod y dystiolaeth ar gyfer therapïau seicolegol. Mae gen i ddiddordeb hefyd mewn aflonyddwch cwsg sy'n gysylltiedig â PTSD, a PTSD fel comorbidrwydd anhwylderau eraill.
