Research Interests
My research broadly concentrates on two main areas, attention and vision. My PhD focuses on auditory attention, particularly problems associated with sustaining attention over a long period. More specifically what happens when more effort is required to sustain attention and how lapses in attention affect different aspects of cognition.
In terms of vision I am interested in how our visual system attempts to form efficient representations and the statistical regularities it exploits to achieve this. My research in this area extends to perception, particularly in the way in which we view faces.
I am interested in both vision and attention from a neuropsychological perspective. I have been involved in the set up of the transcranial magnetic stimulation (TMS) lab. At present looking at identifying neural connectivity in early visual process. My research involves multiple disciplines, psychophysics, eye tracking, ERP and TMS.
