Rwy'n ddiddorol wrth oruchwylio PhDs sy'n cynnwys y meysydd canlynol:

Modelu prosesau cypledig mewn systemau peirianneg geoamgylcheddol a geodechnegol gan gynnwys:
- Ynni daear
- Systemau rhwystr
- Cadwrfeydd daearegol
- Ymddygiad priddoedd wedi'u haddasu.
- Ymddygiad pridd annirlawn.
- Ymddygiad thermo-hydro-fecanyddol deunyddiau mandyllog.
- Ymddygiad rhewi-dadmer pridd.

Hyd yn oed os nad yw'ch syniad wedi'i alinio'n flaenorol â'r meysydd hyn - cysylltwch â ni - gall fod yn rhywbeth y gallaf ei oruchwylio o hyd (neu gyd-oruchwylio gyda chydweithiwr).
