Our team

Prof Sarah Lewis, Academic Director

Prof Sarah Lewis’s research is in medical imaging, specifically breast and lung cancer imaging. She has a primary focus in understanding how new technological imaging developments, such as Phase Contrast and Artificial Intelligence (AI), change the nature of radiology service provisions, such as screening programs, and the performance of the humans who use them.  Sarah’s research translates laboratory findings into clinical practice through changes in behaviour of practitioners, such as radiologists and radiographers.

Dr. Yun Trieu, Post-doc and Chief Technology Officer

Yun’s research aims to exploring innovative algorithms to improve the detection of early clinical indicators of malignancy on medical images and  a cost-effective method for clinicians, educators and medical students to build portable mammogram reading workstations that suit with the remote delivery of high-quality training and education. Her current work is focused on developing individualized mammogram training test sets and she also leads BREAST’s research and training activities in Vietnam.

Dr. Tong Li, Post-doc and Chief Operating Officer

Tong’s research interest covers epidemiology, breast cancer screening, breast density and digital breast tomosynthesis. Her current work is around developing new test sets and she leads BREAST’s research and training activities in China.



Dr Natacha Borecky, Clinical Director

Dr Natacha Borecky has extensively worked the field of radiology with a special interest in Breast Imaging.  She currently works for the Sydney Breast clinic and for BreastScreen NSW, TAS, NT and is the designated radiologist for BreastScreen NT and Norfolk. She has contributed in the creating the Gold Coast and Leura Test set for BREAST and participated in several study with The University of Sydney. Currently, she has completed the new NT test set which will be released this year.

Dr Mel Robinson, Project Manager

Mel is the project manager for BREAST. She has extensive knowledge in various research fields, with over 15 years experience in conducting research, project management and finances. She also holds a Level 1 accreditation for research management (ARMS), bringing a range of skills to manage and support the BREAST research program.

Dr Jennie Noakes, Research Affiliate

Dr Jennie Noakes is currently the designated radiologist for the Northern Sydney LHD and BreastScreen. She has extensive knowledge and experience in this area and extremely excited to have her on board.



Associated Researchers

Prof. Patrick Brennan

Patrick is an award-winning Professor of Medical Imaging Sciences and researcher with a focus on medical imaging optimisation and radiological perception. He co-directed BREAST from 2011-2019 and is now Chief Investigator on BREAST research projects.

Dr. Ziba Gandomkar

Ziba’s research interests include computer-aided medical image analysis, machine learning, deep learning, image perception, and computer-aided detection and diagnosis tools. Her current work involves developing an innovative breast cancer risk prediction model using radiologist’s “gist response”.

Dr Amir Tavakoli Taba

Amir is a lecturer and is working on the clinical implementation of phase-contrast technology as a novel low-dose high-quality 3D modality for breast imaging. His research interests include image perception and personal and social factors pertaining to observer performance. He leads BREAST’s research and training activities in Iran.

Dr. Ernest Ekpo 

Ernest is a lecturer and his research interests include breast density, breast cancer biomarkers, optimisation of breast cancer detection, medical image perception, dose optimisation, radiographic and ultrasound image interpretation, and novel radiological tools for breast composition analyses and image display.

Dr. Mo’ayyad (Moe) Suleiman

Moe’s research involves radiation dose optimisation for screening mammography. He is currently investigating dose exposure and diagnostic efficacy of screening in older women and leads BREAST’s research and training activities in Jordan.

Ms. Somphone (Ling) Siviengphanom

Ling is the Project Manager for the Gist projects within BREAST. Her expertise in finance, strategic planning and management enables the NBCF and NHMRC-funded projects to achieve the team’s objectives and reach project milestones.

Mr. Dennis Wong

Dennis is an HDR student and the Administration Officer at BREAST.  He provides administration support for the team. His thesis and research interests include eye tracking and the use of computer aided-diagnostics for breast density differentiation.
