Biographical Information

I am currently a PhD student working with Dr. Edmund Lalor. I received my primary degree in Computer Science and French in 2003 from University College Dublin. I also completed a Higher Diploma in Psychology in 2011 before embarking on this PhD.

My PhD research investigates the distribution of spatial attention across the visual field in healthy subjects, both behaviourally and electrophysiologically (EEG). This involves the use of a novel evidence accumulation technique which allows the measurement of visual and attentional responses to many visual stimuli presented simultaneously. The goal of this research is to discover neurophysiological correlates of attentional bias, whereby people display a subtle bias for the left or right visual field in their everyday lives. Recent research has shown that the direction and age-related change of this bias can be predictive of Attention Deficit Hyperactivity Disorder and Alzheimer’s Disease. Furthermore, severe attentional bias to one side of the visual field is a common consequence of traumatic brain injury or stroke. At present, only behavioural measures are available for the measure of attentional bias and have proven to be inconsistent. A neurophysiological method of measuring attentional bias would be of great help in post-injury diagnosis and rehabilitation.

Research Interests

  • Spatial attention.
  • Decision making.
  • Unilateral neglect and pseudoneglect.
