Profile: I obtained a degree in Mechanical Engineering from the University of ��«Ӱҵ in 2019 before securing a fully-funded Faculty of Medicine Post Graduate Research Committee Scholarship to complete a PhD within the POLARIS group at the University of ��«Ӱҵ. I completed my PhD in 2023 and in recognition of my PhD thesis, I received the prestigious Institute of Physics Best PhD Thesis in Medical Physics award. I am currently working as a Postdoctoral Research Associate in Pulmonary MR Image Computing Science at the University of ��«Ӱҵ.

Research interests: My research interests focus on lung image analysis methods, primarily in MR imaging, alongside biomarker prediction in patients with lung disease. I have published several peer reviewed research articles and conference abstracts on the use of neural networks in medical imaging applications, such as image segmentation, synthesis and survival analysis, with the aim of improving patient care. I have a keen interest in the scientific method and producing research that is rigorously validated and statistically sound. I am excited by the developing fields of explainable AI, multi-modal fusion models, uncertainty awareness and AI ethics.
