Research Clinical Psychologist


I am a Research Clinical Psychologist within O-CAP.  My main interest is in the association between sleep and psychosis, working as part of the Sleep and Circadian Neuroscience Institute (SCNi).  We are running a series of studies recruiting both university students and individuals currently experiencing delusions and/or hallucinations.  The aim of these studies is to help gain a better understanding of the association between sleep and psychosis and further the development of psychological interventions for sleep. 

I am trial co-ordinator for the OASIS study, the Sleep Study and the Nightmare Intervention Study (NIteS).

OASIS is a randomised controlled trial testing the effects of cognitive behavioural therapy (CBT) for insomnia on the mental health of university students.  The study is recruiting participants with sleep difficulties from many universities across the UK.

The Sleep Study is a pilot randomised controlled trial of a sleep intervention designed specifically for psychiatric inpatients.  The study is set on Vaughan Thomas ward, Oxford Health NHS Foundation Trust.  The intervention includes CBT for sleep problems and bright light therapy. 

NIteS is a pilot randomised controlled trial of CBT targeting nightmares, for people experiencing persecutory delusions.  I am the trial therapist for this study.   

I am an HCPC registered Clinical Psychologist and completed my clinical doctorate at the Institute of Psychiatry.  My research through my clinical training investigated the occurrence of nightmares in individuals who experience delusions and/or hallucinations.
