My research explores a number of different aspects of cognitive neuropsychology, particularly memory/amesia, face recognition and assessment of executive functions. I use a range of methodologies and techniques including standard experimental group designs, single case studies, virtual reality and brain-imaging. My research participants include individuals with brain damage, healthy controls and people with superior abilities.

Research Interests

My DPhil research with Professor Alan Parkin concentrated on a phenomenon known as the "reminiscence bump" in autobiographical memory and, more specifically, looked at why memories from early in life tend to be recalled in greater abundance, with increased speed and with greater detail than those from the middle portion of life. I followed my doctorate with a postdoctoral fellowship with Professor Antonio Damasio and Professor Ralph Adolphs in Iowa working on a range of projects including processing of emotions from faces, confabulation in a patient with an Anterior Communicating Artery Aneurysm and topographical knowledge

My major research concentrates on disorders of human memory. I am conducting detailed case studies of an epileptic patient who exhibits Long-Term Amnesia (rapid forgetting of information over a period of a few weeks), a patient with a very selective Short-Term Memory problem, a patient with a selective inability to remember numbers, a patient who has an inability to experience emotion when remembering autobiographical memories and finally a severely amnesic encephalitic patient on whom I am applying rehabilitation paradigms. A further aspect of my work is the study of both developmental and acquired prosopagnosia to inform theories of normal face-processing. For the last eleven years, I have been using virtual reality to create an ecologically-valid real-world test of dysexecutive problems; as well as clinical applications I am using this assessment to look at the impact on healthy individuals of alcohol, nicotine, the recreational drug ecstasy and drug therapy for prostate cancer. Two final projects are exploring synaesthesia from a neurocognitive perspective and using meditation training to improve the efficiency of Brain-Computer Interfaces using used for controlling neuroprosthetic devices.
