Dr Lewis has been appointed to the National Examination Committee of the Medical Radiation Practice Board of Australia from February 2014-February 2017

Research interests

My research interests are in the areas of ethical and optimal imaging. As a clinical radiographer, clinical academic and researcher, my areas are in the articulation of clinical ethics in the radiography/radiology service setting and the impact of ethics and professional boundaries upon the role of the radiographer. I have a strong interest in optimal imaging in CT, mammography and paediatrics, both from a radiation dose and best practice perspective. Qualitative research methodologies are a feature of my published work, which includes conceptual frameworks and policy design in clinical education, professional role models, reflective practice and inter-professional learning. Recently I have become involved with research in breast imaging and perception as well as an interest in Emotional Intelligence and radiologists’ work roles.
