Darlithydd
Ysgol y Gwyddorau Cyfrifiadol a Mathemategol

Rwy'n Ddarlithydd yn yr Ysgol Cyfrifiadureg a Gwybodeg ym Mhrifysgol Caerdydd. Cefais fy ngradd PhD mewn Prosesu Iaith Naturiol (cangen o AI) yn yr adran Cyfrifiadureg ym Mhrifysgol Lerpwl. Yn flaenorol, derbyniais fy MSc mewn Data Mawr a Chyfrifiadura Perfformiad Uchel ym Mhrifysgol Lerpwl.

Mae fy niddordebau ymchwil yn gyffredinol mewn moeseg, rhagfarn a thegwch yn NLP yn ogystal â dealltwriaeth iaith naturiol, megis semanteg geirfaol, dysgu cynrychiolaeth iaith, amlfoddoldeb, rhesymu synnwyr cyffredin, dulliau amlieithog, cynhyrchu testunau, dehongli a dadansoddi modelau.
