Rwy'n cyd-gyfarwyddo'r Grŵp Atgyweirio Ymennydd (BRG), lle rydym yn canolbwyntio ar ddeall a thrin clefydau niwroddirywiol, yn enwedig clefyd Parkinson a Huntington. Mae gennym ddiddordeb mewn deall amlygiad diffygion echddygol a di-fodur (gwybyddol, niwroseiciatreg) mewn clefydau dirywiol gan ddefnyddio briwiau, fector firaol a modelau cnofilod a addaswyd yn enetig. Rydym hefyd yn ymchwilio i allu celloedd newydd (hESC- a hiPSC-deillio) a therapïau genynnau i leddfu'r namau hyn a gwneud y gorau o'r triniaethau hyn i'w cymhwyso yn glinigol.
Fi yw Dirprwy Bennaeth yr Is-adran Niwrowyddoniaeth
Rwy'n PI yn y Sefydliad Darganfod Meddyginiaethau (MDI) ac yn gyd-fyfyriwr yn y Sefydliad Ymchwil Dementia (DRI).
Rwy'n gweithredu fel Arweinydd Thema Cyswllt ar gyfer Meddwl, Brain a Niwrowyddorau
Fi yw'r Dirprwy Gadeirydd a Chynrychiolydd Biosi ar y Panel Lles Anifeiliaid ac Ymchwil (AWARP)

Ymchwil
https://www.thebrainrepairgroup.com/
Rwy'n gyd-gyfarwyddwr y Brain Repair Group. Mae ein labordy yn canolbwyntio ar ddeall a thrin clefydau niwroddirywiol, yn enwedig clefydau Parkinson a Huntington. Mae gennym ddiddordeb mewn deall amlygiad diffygion echddygol a di-fodur (gwybyddol, niwroseiciatreg) mewn clefydau dirywiol gan ddefnyddio briwiau, fector firaol a modelau cnofilod a addaswyd yn enetig. Rydym hefyd yn ymchwilio i allu celloedd newydd (hESC- a hiPSC-deillio) a therapïau genynnau i leddfu'r namau hyn a gwneud y gorau o'r triniaethau hyn i'w cymhwyso yn glinigol.
Mae rhai cwestiynau ymchwil cyfredol sy'n cael eu trafod yn cynnwys:
A all impiadau dopamin sy'n deillio o HPC leddfu camweithrediadau nad ydynt yn motor mewn clefyd Parkinson?
A yw neuroinflammation yn chwarae rhan mewn dyskinesias a achosir gan domines sy'n deillio o HPC?
Beth yw effaith cynhyrchu dopamin o fectorau AAV ar swyddogaeth wybyddol sy'n ddibynnol ar striatal?
A allwn ni fodiwleiddio mynegiant genynnau i wella twf allan niwrite a ffurfio synapse o impiadau dopamin sy'n deillio o HPC?
A all trawsblaniadau niwronau troellog canolig sy'n deillio o HPC ffurfio cysylltiadau synaptig a lliniaru camweithrediadau nad ydynt yn foduron mewn modelau o glefyd Huntingtons?
Addysgu
Ar hyn o bryd fi yw Arweinydd y Modiwl ar fodiwl 3ydd blwyddyn BI3451 'Niwrofioleg Anhwylderau Ymennydd'.
Rwy'n addysgu ar y modiwl Peirianneg Meinwe ar lefel Meistr.
Rwy'n rhedeg wythnos ymarferol i ddysgu profion histolegol ac imiwnocemegol a sgiliau microsgopeg gan ddefnyddio meinweoedd ymennydd cnofilod.
Rwy'n diwtor personol ar gyfer myfyrwyr israddedig Niwrowyddoniaeth a Biofeddygol.

Bywgraffiad
Ymchwiliodd fy PhD (2005-2010, yr Athro M Da) gamweithrediad rhwydwaith niwral gan ddefnyddio modelu mathemategol mewn model llygoden o glefyd Alzheimer, gyda ffocws penodol ar gamweithrediad a achosir gan amyloid yn y ffurfiad amydala a hippocampal.
Nod fy ymchwil ôl-ddoethurol (2010-2015, yr Athro S Dunnett) oedd deall camweithrediad ganglia sylfaenol ym mhwyster Parkinson a Huntington ac archwilio'r defnydd o therapïau sy'n deillio o gelloedd ffetws dynol a bôn-gelloedd newydd i leddfu'r namau ymddygiadol.
Dyfarnwyd Uwch Gymrodoriaeth Ymchwil i mi gan Parkinson's UK (2015-2018) i ymchwilio i allu cynhyrchion therapi celloedd bôn-gelloedd dynol i leddfu namau gwybyddol mewn modelau cnofilod o glefyd Parkinson.
Wedi hynny dechreuais Uwch Ddarlithyddiaeth yn yr adran niwrowyddoniaeth a dyrchafiad yn Ddarllenydd yn 2024. Mae fy labordy yn archwilio sawl llwybr newydd. Rydym yn ceisio sefydlu therapïau celloedd newydd i drin clefydau Huntington, gan ddefnyddio triniaethau DREADDs newydd i ddeall mecanwaith gweithredu therapïau celloedd, ymgymryd â delweddu PET/MR a defnyddio technolegau olrhain gynddaredd i archwilio integreiddio synaptig. Rydym hefyd yn astudio effaith therapïau genynnau newydd ar swyddogaeth gellog ac ar gamweithrediad gwybyddol.
