As a postdoctoral researcher in the Bioinformatics and Cellular Genomics laboratory and part of the BRAIx collaboration, I use cutting-edge Artificial Intelligence (AI) and data science approaches to develop software able to accurately diagnose breast cancer on mammogram scans.

My PhD focused on using AI to characterise organs in a post-mortem computed tomography database in the Department of Medical Imaging and Radiation Sciences at Monash University. I started working on image processing during my Master’s studies in Engineering (Industrial Automation), using machine vision and several machine learning techniques for robotic applications.

I have obtained a high level of experience in using deep learning techniques, such as convolutional neural networks for localisation, feature extraction, and data representation. During my PhD and postdoctoral appointment, I extended my knowledge of deep learning to implement different network architectures such as VGG, ResNet, and convolutional autoencoders for supervised, semi-supervised, and unsupervised learning.

I have more than seven years’ experience in programming using Matlab, Python and Pytorch, including the use of specialised libraries such as OpenCV and scikit-learn. In addition, I have experience in the use of high-performance data processing facilities, utilising Unix-based systems, GPUs, and computing clusters for large-scale data analysis.
