Crynodeb o'r Ymchwil
Mae cof yn sylfaenol amherffaith; nid yw'n gweithio fel recordiad fideo. Weithiau rydyn ni'n cofio manylion nad oeddent erioed wedi digwydd neu'n anghofio digwyddiadau yr oeddem yn credu eu bod yn fythgofiadwy. Eto mae'r diffygion hyn yn datgelu rhywbeth dwfn: nid stordy goddefol yw cof ond system weithredol ac addasol sy'n naturiol dueddol o gamgymeriad.
Mae fy ymchwil yn ymchwilio i sut mae pobl yn dysgu, storio ac adfer gwybodaeth, a sut mae'r prosesau hyn yn cael eu dylanwadu gan sylw, gwybodaeth flaenorol, ac iaith ar draws y cyfnod oes, o blentyndod i oedolion hŷn. Mae gen i ddiddordeb arbennig mewn deall pam mae pobl yn gwneud gwallau cof a sut y gellir rhagweld y gwallau hyn yn fanwl gywir. I astudio'r cwestiynau hyn, rwy'n cyfuno dulliau arbrofol a chyfrifiadurol. Mae fy arbrofion yn archwilio sut mae pobl yn cofio dilyniannau o wybodaeth (fel geiriau, delweddau, neu ddigwyddiadau) o dan amodau amrywiol.
Rwyf hefyd yn datblygu modelau cyfrifiadurol, fframweithiau mathemategol ffurfiol sy'n efelychu sut mae cof yn gweithredu. Mae'r modelau hyn yn cynhyrchu rhagfynegiadau manwl gywir, profiadwy am ymddygiad dynol ac yn galluogi cymariaethau uniongyrchol rhwng damcaniaethau cof cystadleuol. Trwy integreiddio technegau mathemategol lluosog, fy nod yw adeiladu cyfrif cyffredinol o gof sy'n esbonio patrymau perfformiad a gwallau ar draws gwahanol dasgau a chyd-destunau.
Mae'r gwaith hwn yn hyrwyddo ein dealltwriaeth ddamcaniaethol o sut mae'r cof yn gweithredu tra hefyd yn llywio cymwysiadau ymarferol mewn addysg, heneiddio, a thechnolegau gwybyddol, gan helpu i ddylunio strategaethau ac offer sy'n cefnogi dysgu a chof trwy gydol oes.

Bywgraffiad
Cwblheais fy holl addysg uwch yn yr Université de Moncton o dan fentoriaeth Dr. Jean Saint-Aubin. Enillais Baglor yn y Celfyddydau mewn Seicoleg (2013–2016), gan gwblhau traethawd ymchwil a oedd yn archwilio cofio yn ôl - y gallu i gofio gwybodaeth mewn trefn wrthdro, tasg a ddefnyddiwyd yn helaeth mewn profion cudd-wybodaeth ar y pryd. Yna cwblheais radd Meistr yn y Celfyddydau mewn Seicoleg (2016–2018), gan ymchwilio i sut mae ffactorau geiriadurol-semantig yn dylanwadu ar "allu" y cof, gan ddangos bod perfformiad yn dibynnu mwy ar briodweddau ieithyddol a semantig nag ar hyd geiriau neu hyd mynegi.
Yn ystod fy ngradd Meistr, cwblheais interniaeth ymchwil pedwar mis ym Mhrifysgol Goffa Newfoundland (Canada) o dan oruchwyliaeth Dr. Aimée Surprenant a Dr. Ian Neath. Gyda'n gilydd, fe wnaethom archwilio'r egwyddorion cyffredinol sy'n sail i'r cof geiriol a chynnig y rhagdybiaeth geiriadurol, gan awgrymu bod perfformiad cof yn cael ei siapio i raddau helaeth gan effeithiau cynnil, yn aml cudd, o brofiad ieithyddol blaenorol.
Dilynais fy PhD mewn Seicoleg (2018–2021) yn yr Université de Moncton, gan ganolbwyntio eto ar gofio yn ôl. Yn ystod y cyfnod hwn, datblygais gyfrif damcaniaethol newydd o atgoffa cyfresol a chynlluniais sawl arbrawf i brofi ei ragfynegiadau. Fel rhan o fy ngwaith doethurol, ymgymerais ag ymweliadau ymchwil â Phrifysgol Wollongong (Awstralia), lle gweithiais gyda Dr. Leonie Miller a Dr. Steven Roodenrys i archwilio ymhellach sut mae gwybodaeth ieithyddol flaenorol yn dylanwadu ar berfformiad y cof. Treuliais hefyd bedwar mis ym Mhrifysgol Missouri (Unol Daleithiau) yn cydweithio â Dr. Nelson Cowan, lle gwnaethom gychwyn sawl prosiect ar sut mae sylw yn cael ei ddyrannu rhwng gwybodaeth eitem ac archeb, sut mae capasiti cof gweithio yn cyfyngu ar drosglwyddo i gof hirdymor, a sut mae gwybodaeth flaenorol yn siapio perfformiad ar draws y cyfnod oes.
Ar ôl cwblhau fy PhD, dyfarnwyd cymrodoriaeth ôl-ddoethurol fawreddog i mi gan Gyngor Ymchwil Gwyddorau Naturiol a Pheirianneg Canada (NSERC) i barhau â'm cydweithrediad â Dr. Cowan. Yn ystod y cyfnod hwn, cefais wahoddiad hefyd i weithio am dri mis gyda Dr. Randall Jamieson (Prifysgol Manitoba), lle gwnaethom ddatblygu'r Fframwaith Cyfrifiadurol Mewnblanedig Cof (eCFM) - fframwaith sy'n integreiddio modelau cof ac iaith i gynhyrchu rhagfynegiadau manwl, profiadwy ar draws ystod o dasgau.
Mae fy ymchwil gyfredol yn ymestyn y gwaith hwn trwy ddatblygu modelau cyfrifiadurol hygyrch sy'n gallu cyffredinoli ar draws paradigmau cof amrywiol. Y nod ehangach yw pontio seilos damcaniaethol mewn gwyddoniaeth wybyddol a symud tuag at gyfrif unedig, mecanyddol o gof a gwybyddiaeth ddynol.
Anrhydeddau a dyfarniadau
Dros y blynyddoedd, rwyf wedi bod yn ffodus i dderbyn sawl anrhydedd sy'n cydnabod fy ymchwil a'm haddysgu. Rwy'n ddiolchgar iawn i'm mentoriaid a'm cydweithwyr y mae eu harweiniad a'u partneriaeth wedi siapio a chefnogi'r gwaith hwn.
Ers cwblhau fy PhD, mae fy ymchwil wedi cael ei gydnabod yn rhyngwladol trwy sawl rhagoriaeth. Cefais fy enwi'n Rising Star (2024) gan y Gymdeithas Gwyddoniaeth Seicolegol, gan gydnabod cyfraniadau rhagorol ar ddechrau gyrfa i wyddoniaeth seicolegol. Mae sawl un o'm cyhoeddiadau wedi cael eu dewis fel erthyglau Dewis y Golygydd mewn cyfnodolion blaenllaw, gan gynnwys Experimental Psychology (2022, 2024, 2025, 2026), Journal of Experimental Psychology: Human Perception and Performance (2023), a Journal of Intelligence (2024).
Rwyf hefyd wedi cael fy nghydnabod am ragoriaeth mewn addysgu ac ymgysylltu â myfyrwyr ym Mhrifysgol Caerdydd, lle cefais fy enwebu ar gyfer yr Aelod Staff Mwyaf Ymgysylltu (2022–2023) a'r Profiad Dysgu Mwyaf Rhagorol (2024–2025, 2025-2026) fel rhan o'r Gwobrau Cyfoethogi Bywyd Myfyrwyr, sy'n dathlu unigolion sydd wedi gwneud gwahaniaeth cadarnhaol sylweddol i brofiad prifysgol myfyrwyr.
Cyn ymuno â Chaerdydd, derbyniodd fy ymchwil doethurol sawl rhagoriaeth fawr yng Nghanada. Cefais Fedal Aur y Llywodraethwr Cyffredinol (2021) am gyflawni'r statws academaidd uchaf ar lefel graddedig, Gwobr Vo-Van (2022) am y traethawd hir gorau ar draws pob disgyblaeth yn Université de Moncton, a Gwobr Papur Gorau Gwyddoniaeth Ddatblygiadol (2021) am ein gwaith, dan arweiniad Dr. Alicia Forsberg, ar sut mae gallu cof gwaith plant yn cyfyngu ar gadw tymor hir. Yn gynharach yn fy ngyrfa, cefais Wobr Erthygl Orau Canadian Journal of Experimental Psychology (2020) am waith dan arweiniad Dr. Tyler Ensor, Gwobr y Llywydd gan yr Université de Moncton (2020) am y cyhoeddiad myfyrwyr gorau am fy ymchwil ar ôl cofio, a thystysgrifau lluosog o ragoriaeth academaidd gan Gymdeithas Seicolegol Canada ac Université de Moncton ar gyfer fy ngraddau Meistr ac israddedig.
