Personal profile

Research interests


I have an interest in the evaluation and lateralisation of cognitive function in epilepsy using functional MR neuroimaging methods, both in task-based and resting state fMRI, with particular emphasis on pre-operative evaluation for resective surgery.

We are currenlty attempting to evaluate the efficacy of using task-based fMRI paradigms (some novel), resting-state fMRI and diffusion tensor imaging in predicting post-operative cognitive risk of resective surgery.

Traumatic Brain Injury

I am interested in the detetction of Post-Traumatic Amnesia (PTA) and its prognostic use in ongoing cognitive sequelae. I have been involved in developing guidance on the assessment and management of PTA in two major trauma centres and regional rehabilitation units. I have also been involved in projects developing new protocols for assessing the ongoing risk of PTA.

I am engaged with research in the behavioural assessment and detection of cognitive sequelae of traumatic brain injury. I have been involved in developing a cognitive screening tool for children and presented this as a paper at the International Neuropsychological Society Conference (2016).

I have been involved to a lesser degree in research and guidance in neurorehabilitation of traumatic brain injury, with respect to the rehabilitation of working memory (Phase II - RCT), guidelines for management challenging behaviour, assessment and mamangement of prolonged disorders of consciousness (NCHC NHS Trust) and most recently (2017) advice in promoting exerercise following TBI to improve recovery.


I am currently a Research Psychologist on a clinical trial assessing Kuvan's effect on the cognition of children with Phenylketonuria, for which I conduct assessments of intellectual functioning and consult on the monitoring of development using psychometeric methods and techniques.
