My main research interests are applied and experimental neuropsychology, specifically neuropsychological impairment in psychiatric illness and its biological underpinnings.
This work has extended to a series of projects examining aspects of neuropsychological change and cognitive preservation in ageing. We are particularly interested in assessing intra-individual reaction time variability, applying ex-Gaussian modelling (see recent publications).
