I am a health service researcher and clinical psychologist specialising in the field of psychosis. I am section lead for the Centre for New Treatments and Understanding in Mental Health. I have over 25 years of experience in clinical research and my research has been key in highlighting the psychological and social causes of psychosis. This is important because less than a decade ago, it was widely accepted that psychosis was a purely biologically-driven mental health problem. My research has shown that problems in relationships with early caregivers (attachment relationships) and experiences of abuse can lead to more severe symptoms and more difficulties in engaging in treatments. Relatedly, I have used these findings to develop and evaluate more accessible psychological treatments for people with psychosis in both community and inpatient mental health settings. There is huge gap translational between evidence-based psychological therapies for psychosis and delivery of therapy in the NHS and my research has focused on overcoming this gap and barriers to delivery. I am co-director of the Complex Trauma and Resilience Research Unit (C-TRU) at Greater Manchester Mental Health NHS Foundation Trust, which has the strategic remit of bridging the gap between research and clinical practice by translating research findings into clinical settings and driving new innovations through grant income. I have an extensive and sustained track record of supervising postgraduate and undergraduate research projects related to my own programme of research and I continue to practise as a clinical psychologist in mental health services. 


After completing my PhD exploring the relevance of attachment theory in psychosis, I obtained an NIHR funded fellowship to develop and evaluate an intervention to improve staff-patient relationships in inpatient settings.  This fellowship was an important stepping stone in obtaining an NIHR programme grant to increase access to psycholgical therapy on acute mental health wards. I qualified as a clinical psychologist prior to starting my PhD and have continued to practice as a clinical psychologist alongside my research.
