Dr Gordon Stevenson is a Post-Doctoral Research Fellow in the School of Women's & Children's Health, UNSW. As a Biomedical Engineer, Dr Stevenson's research revolves around the application of Doppler ultrasound to provide new, clinically relevant ultrasound imaging biomarkers. These tools may aid improved detection or understanding of pathology in pregnancy and neonate. He is interested in the applying machine learning and image processing to 3D medical image data to provide new, automated tools for pregnancy assessment.
