Uwch Ddarlithydd Anrhydeddus
Trosolwg
Rwy'n Anesthetydd ymgynghorol ac yn Uwch Ddarlithydd yn Ysgol Feddygaeth Prifysgol Caerdydd.
Mae fy ymchwil yn canolbwyntio ar ymyriadau amlbroffesiynol cymhleth i wella adnabod a thrin cyflyrau mamol gan gynnwys gwaedu a haint yn ystod genedigaeth.
Rwy'n gyd-brif ymchwilydd ar gyfer Treial OBS UK ac yn glinigydd arweiniol ar gyfer yr astudiaeth MSep.
