Research Interests:

- Neurophysiology of selective attention and multisensory integration, and the role of alpha oscillations in these functions
- EEG-based brain computer interfacing for alternative communication and control
- Characterization of behavioral and electrophysiological markers of brain dysfunction, towards diagnosis & endophenotyping through pattern classification
- Sustained attention function in normal individuals, after traumatic brain injury, and in attention deficit hyperactivity disorder

Academic Background:

PhD in Biomedical Engineering, University College Dublin (2005)
