Trosolwyg
Rwy'n cynnal ymchwil sylfaenol, gan ddefnyddio olrhain llygaid a thasgau cyfrifiadurol, i ymchwilio i swyddogaeth weledol a chanfyddiad symud sy'n deillio o ddatblygiad arferol ac annormal y system weledol ddynol.
Rhaid i'r holl fewnbwn gweledol gael ei brosesu gan y retinas cyn ei drosglwyddo i gortecs gweledol yr ymennydd. Fodd bynnag, mae symudiadau llygaid yn cyfeirio ein retinas yn gyson at wahanol wrthrychau yn yr amgylchedd. Eto, er gwaethaf y cynnig incessant hwn, mae'r amgylchedd fel arfer yn cael ei ystyried yn llonydd.
Gall nifer o gyflyrau niwro-offthamig gynhyrchu osgiliadau parhaus, patholegol o'r llygaid (arwydd o'r enw nystagmus) a allai arwain at gynnig rhithus o'r amgylchedd neu beidio.
Amcan fy ymchwil cyfredol yw cysylltu symudiadau llygaid â mesurau swyddogaeth weledol a chanfyddiad symudiadau, yn y rhai sydd â nystagmus a hebddynt, mewn ymdrech i ddeall yn well y canfyddiad o llonyddwch, osgilossia a chanlyniadau symud amhriodol o'r llygaid.

Ymchwil
I conduct basic research, using eye tracking and computer-based tasks, to investigate visual function and motion perception resulting from normal and abnormal development of the human visual system.
All visual input must be processed by the retinas before transmission to the visual cortex of the brain. However, eye movements are constantly directing the retinas to different objects in the environment. Yet, despite this incessant motion of the retinas, the environment is usually perceived as stationary.
A number of neuro-ophthamic conditions can produce continuous, pathological oscillations of the eyes (a sign called nystagmus) that may or may not result in an illusory motion of the environment (a symptom called oscillopsia).
The objective of my current research is to relate eye movements to measures of visual function and motion perception, in those with and without nystagmus, in an effort to better understand the perception of stationarity, oscillopsia and the consequences of inappropriate motion of the eyes
