Medical Radiation Physicist | Monte Carlo Simulations & Dosimetry | AI/ML for Medical Imaging | Scientific Computing

Profile Summary

I am a Medical Radiation Physicist with expertise in Monte Carlo simulations, radiation dosimetry, medical imaging physics, and AI/ML-driven data analysis. I help pharmaceutical, medical device, and research organisations solve complex problems at the intersection of physics, computing, and healthcare. Core competencies: Radiation dosimetry and Monte Carlo modelling — Geant4 and TOPAS simulations for dose estimation, radiation transport, shielding design, and targeted radionuclide therapy optimisation. My Master's thesis involved cellular-scale microdosimetry and biokinetic modelling for Pb-212 targeted alpha therapy (TAT), combining Geant4 Monte Carlo with multi-compartment pharmacokinetic models. Medical imaging and AI — Development of machine learning pipelines for medical image segmentation, classification, and analysis using PyTorch, TensorFlow, and MONAI across CT, MRI, PET/SPECT, and mammography modalities. Scientific computing and data analysis — Python and MATLAB pipelines for research data processing, statistical modelling, signal analysis, and automated reporting. Experienced in translating complex datasets into actionable insights and publication-ready outputs. Technical and scientific writing — Research manuscripts, technical reports, regulatory documentation, and grant support grounded in radiation physics and medical device contexts. I hold a Master of Medical Radiation Physics (MMRP) from the University of Adelaide (ACPSEM-accredited program), with additional clinical experience in medicine and current industry experience in pharmaceutical manufacturing under GMP. I combine rigorous scientific training with practical computational skills to deliver accurate, well-documented, and reproducible results. Available for consulting, data analysis, simulation, and writing projects worldwide.
