Biographical details

Professor Brennan's research involves exploring novel technologies and techniques that enhance the detection of clinical indicators of disease, whilst minimising risk to the patient.His research has involved most major imaging modalities including X-ray, computerised tomography, ultrasound and magnetic resonance imaging, with a particular focus on breast and chest imaging. In line with Government priorities, his research findings have translated into improved diagnosis and management of important disease states such as cancer, musculo-skeletal injury, arthritis and multiple sclerosis.

He is recognized as a leader in clinical translation of medical imaging optimization and radiological perception. Professor Brennan has been invited to deliver talks across 4 continents. He has presented at the major international imaging meetings including the annual meetings of the Radiological Society of North America, European Congress, UK Radiological Congress, International Society of Optical Engineering and Medical Imaging Perception Society.

He has published over 170 original papers, and these have been accepted by the leading radiological journals such as Radiology, American Journal of Roentgenology, Academic Radiology, European Radiology and British Journal of Radiology.His work is having an important impact on clinical practice across the globe. Over the last decade his work has generated AUD10.0million and has led to the supervision of more than 50 honours students and 35 graduate research students, including 25 PhD projects.

He has won 2 medals of excellence for teaching and has acted as undergraduate, graduate and PhD examiner in 9 universities across Europe, Asia and the Americas.He is currently Professor of Medical Imaging and Associate Dean, International at the Faculty of Health Sciences, University of Sydney. He is also co-director of BREAST, the Australian National Initiative to enhance cancer detection in breast imaging.

Research interests

Professor Brennan is the leader of the Imaging, Optimisation and Perception Group MIOPeG

Teaching and supervision

In his role as Associate Dean of International Research Development, Professor Brennan is responsible for setting out a strategy for how the Faculty can continue to build on its impressive history of international collaboration through exposure to these opportunities as they arise.

He will also be working towards ensuring there is a high level of awareness of the work done globally by the Faculty of Health Sciences.
