Biography
I completed my PhD at the University of Cambridge in 2018, where I was supervised by Professor Roberto Cipolla and Dr. Antonio Criminisi. My PhD was supported by a Microsoft Research Ph.D. Scholarship and I collaborated with researchers at Microsoft Research Cambridge (UK) extensively. Following my PhD I was a Postdoctoral Research Fellow at the Vector Institute, working with Prof. Graham Taylor, and Prof. Mihai Nica, and before that a Visiting Researcher at Google Brain Toronto/AR Core.
Research Impact
In my PhD I made research contributions in structured sparsity for Convolutional Neural Networks (CNNs) that are now widely used in all modern deep learning architectures for computer vision. I also worked on pioneering work in understanding the difficulty of adversarial robustness, and some of the earliest work applying CNNs to brain tumour segmentation. More recently I worked with NASA/SETI on applying deep learning to exoplanet classification, the resulting method continues to be used in processing data from the Transiting Exoplanet Survey Satellite (TESS) space telescope.
Current Research Interests
My current research focus is on unstructured sparse training of deep neural networks, and efficient deep learning more generally, with a focus on problems in computer vision in particular.
Industrial Research Experience
Outside of academia, I have a range of industrial research experience, including at Microsoft Research Cambridge (Intern/Business Guest), Google Brain Toronto (Visiting Resarcher), and a UK self-driving startup Wayve (Research Scientist). Outside of research, I've contributed to open source projects such as the Linux kernel and the Point Cloud Library (PCL).

Areas of Research
My current research focus is on unstructured sparse training of deep neural networks, and efficient deep learning more generally, with a focus on problems in computer vision in particular.
I have worked on many computer vision applications such as conditional imitation learning for self-driving vehicles, medical imaging (brain tumour segmentation), 3D computer vision (point cloud segmentation), assistive technology (fall detection).
