Ruth is a HCPC registered clinical and forensic psychologist. She spent 30 years working in the NHS in a variety of clinical settings in Wales, 20 years of which were spent working in adult forensic mental health. She was the lead consultant psychologist in a medium secure hospital where she also acted as a non-medical Approved Clinician under the Mental Health Act (1983 as amended 2007). She has extensive experience as an expert witness, predominantly in criminal cases.

Ruth's research interests lie broadly in understanding practice in relation to service improvement in mental health care, and psychopathy, personality and neuropsychology.

Ruth is currently involved in supervising three PhD projects on clinical and offending outcomes for patients discharged from medium secure care, psychological mechanisms involved in weight gain amongst secure mental health inpatients, and proactive and reactive control in secure mental health inpatients.
