Trosolwyg
Rwy'n ffarmacolegydd moleciwlaidd gyda dros 25 mlynedd o brofiad darganfod cyffuriau, yn bennaf ym maes niwrowyddoniaeth. Yn ystod y cyfnod hwn, rwyf wedi cyfrannu at y camau cynharaf o ddarganfod cyffuriau (adnabod targedau a dilysu targed) yr holl ffordd hyd at dreialon clinigol Cam 1 a Cham 2.
Rwyf wedi gweithio ar nifer o wahanol fathau o dargedau cyffuriau (ensymau, derbynyddion wedi'u cyplysu â phrotein a sianeli ïonau) sy'n cwmpasu ystod o glefydau niwroddirywiol (e.e. clefydau Alzheimer, Huntington a Parkinson) ac anhwylderau seiciatrig (anhwylder deubegynol, sgitsoffrenia, anhwylder gorbryder cyffredinol, iselder). Mae gen i ddiddordeb arbennig yn yr agweddau trosiadol o ddarganfod cyffuriau preclinical sy'n rhoi hyder y gall ymgeisydd cyffuriau penodol ymgysylltu â'r targed a chynhyrchu darlleniad swyddogaethol mewn dyn.
Fy hoff gyffur a mecanwaith gweithredu? Wel, byddai'n rhaid i hynny fod yn diazepam a'r derbynnydd GABAA ... Neu efallai mai cetamin a'r derbynnydd NMDA ydyw... Neu lithiwm a sut bynnag mae hynny'n gweithio mewn anhwylder deubegynol ... Heb sôn am donepezil, felly wna i ddim.

Bywgraffiad
Yn dilyn PhD mewn patholeg niwrocemegol yn yr Adran Patholeg yn Ysbyty Cyffredinol Newcastle, gweithiais am 5 mlynedd (1984-89) yn y Labordy Niwrowyddoniaeth yn y Sefydliad Cenedlaethol ar Heneiddio ar gampws y Sefydliadau Iechyd Cenedlaethol (NIH) ym Methesda, Maryland, gan astudio newidiadau cyn ac ôl-mortem ym niwrocemeg cleifion â chlefyd Alzheimer a syndrom Down.
Yn ystod fy nghyfnod yn yr NIH, dechreuais brosiect yn edrych ar ddatblygu atalyddion acetylcholinesterase ar gyfer trin clefyd Alzheimer. O'r fan honno, ymunais â Chanolfan Ymchwil Niwrowyddoniaeth Merck Sharp a Dohme yn Harlow lle gweithiais o 1989-2006 ar amrywiaeth o agweddau in vitro ac in vivo o ddarganfod cyffuriau niwrowyddoniaeth. Pan gaeodd y safle o ganlyniad anuniongyrchol i'r cyffur Blockbuster Merck, Vioxx, yn cael ei dynnu oddi ar y farchnad, ymunais â Janssen Pharmaceuticals, cangen fferyllol Johnson & Johnson, lle gweithiais o 2006 i 2012 (yn La Jolla i ddechrau ac yna, wedi'i ddenu gan y cwrw, sglodion a siocled, yn Beerse, Gwlad Belg).
Gadewais y diwydiant fferyllol i ymuno â Phrifysgol Sussex i helpu i sefydlu, gyda'r Athro Simon Ward, Canolfan Darganfod Cyffuriau Sussex a oedd, ynghyd ag ychwanegu'r Athro Martin Gosling, wedi ennill enw da am ddarganfod cyffuriau niwrowyddoniaeth a ffarmacoleg sianel ïonau yn benodol.
Yn haf 2017, dewisodd Simon a minnau symud i Gaerdydd, a ddenwyd gan ragoriaeth mecanwaith y clefyd a gwyddoniaeth glinigol ac ansawdd ac ysbryd cydweithredol yr ymchwilwyr y byddwn yn rhyngweithio â nhw. Fodd bynnag, rydym yn cynnal ein cysylltiadau â Martin sy'n parhau i fod yn gydweithredwr allweddol ac yn caniatáu inni ehangu ein diddordeb mewn ffarmacoleg sianel ïonau.
