Dr Moyle holds a Master of Psychology (Clinical Neuropsychology) and a PhD (Psychology) plus full registration with the Psychologists Board of Australia and specialist endorsement to practice in the area of Clinical Neuropsychology.

With extensive experience in neuropsychological assessment of adolescents and adults across multiple clinical populations, Dr Moyle has been an effective practitioner across a range of settings including the Next Step Drug and Alcohol Service (WA), Perth Children’s Hospital and John Hunter Hospital (Newcastle), while also building his own private practice and supervising emerging leaders in the field. Dr Moyle has positively impacted the lives of many people dealing with complex issues ranging from acquired brain injury and cerebral palsy to spinal injuries, and neurodevelopmental conditions to the affects of addiction.

Assessments with Dr Moyle result in purposeful, individual reports that can be used to inform clinical teams and to shape further therapies as required. These reports may also inform matters related to justice such as fitness-to-plead, and inform decisions regarding cognitive capacity. His clients include individuals, the Department of Justice WA, several Perth-based legal firms, rehabilitation agencies, GPs, and paediatricians.

In addition to clinical practice, Dr Moyle has authored over 20 peer-reviewed journal articles and conference abstracts and has served as a reviewer for international peer-reviewed scientific journals.
