Biography
Dr Samantha Jane Alloo is currently a post-doctoral researcher at Monash University. She is an X-ray optics researcher interested in applying the skills she has developed across diverse optical techniques. She earned her PhD in Medical Physics from the University of Canterbury in August 2024, where she focused on creating an efficient computational phase and dark-field retrieval algorithm for the emerging technique of speckle-based X-ray imaging. Her PhD combined aspects of theoretical development, experimental work, software implementation, and data analysis. She has accumulated awards at international conferences for her oral presentation skills, been the primary investigator for a European Synchrotron Radiation Facility experiment, and been awarded multiple grants, thereby self-funding her PhD project.
Her current research explores the Fokker-Planck equation for paraxial X-ray imaging, seeking to determine its practical applications, solution methods, potential extensions for revealing additional sample information, and theoretical boundaries. She is eager to increase her breadth of knowledge, applying her current skillset to various physics-related research fields.
