Ymchwil
@ylabwales rydym yn cynnal ymchwil ar arloesi gwasanaethau cyhoeddus, gan gynnwys drwy nifer o'n rhaglenni, gan gynnwys:
- Arloesi i Arbed
- Iechyd, Celfyddydau, Ymchwil, Pobl (HARP)
- Gwasanaethau Arloesol y Dyfodol (InFuSe)
- Cronfa Her Prifddinas-Ranbarth Caerdydd
Mae'r methodolegau gwerthuso sylfaenol yr wyf wedi'u cymhwyso mewn iechyd byd-eang wedi bod yn dreialon ar hap clwstwr ac wedi camu ar dreialon lletem, bob amser mewn timau rhyngddisgyblaethol. Bûm yn byw ac yn gweithio yn Johannesburg am saith mlynedd ac rwyf hefyd wedi gweithio ar brosiectau ym Mheriw, Burkina Faso, India, China, Zimbabwe a Zambia.

Pwyllgorau ac adolygu
Adolygydd ystadegol, cyfnodolion Lancet
Meysydd goruchwyliaeth
Ar hyn o bryd rwy'n goruchwylio un myfyriwr doethuriaeth broffesiynol, Becky Parish, gan edrych ar brofiadau trawsffiniol o'r GIG sy'n canolbwyntio ar Swydd Gaerloyw lle gellir profi elfennau o ofal GIG Cymru a Lloegr.
Ar hyn o bryd rwy'n goruchwylio un myfyriwr PhD, Cara O'Connor, gan edrych ar brofiadau o ymyrraeth sy'n cefnogi pobl i lynu at eu meddyginiaeth wrth-retrofirysol mewn clinig HIV arloesol yn Ynysoedd y Philipinau.
Mae gen i ddiddordeb mewn goruchwylio myfyrwyr PhD a Doethuriaeth Proffesiynol ym meysydd arloesi gwasanaethau cyhoeddus ac arloesi cymdeithasol.
