Early and accurate cancer detection remains a critical global healthcare challenge, with profound implications for patient outcomes and treatment strategies. While Time-of-Flight Positron Emission Tomography (ToF-PET) offers vital functional and molecular insights for improved cancer staging, its current capabilities are often limited by the timing resolution and sensitivity of existing detector technologies.

Metamaterials, engineered to exhibit properties not found in naturally occurring materials, offer an innovative pathway to overcome these limitations. By designing intricate periodic or quasi-periodic structures, we can precisely control the interaction of radiation with matter, potentially achieving unprecedented timing resolution (sub-70ps) and significantly enhancing signal detection.

This PhD project will take a comprehensive approach, encompassing the design, manufacturing, and characterisation of metamaterial architectures for advanced radiation detection. The research will involve:

• Computational Modelling: Employing simulation tools (e.g., GEANT4, light transport) to explore novel metamaterial designs, predict performance, and optimise key parameters such as timing resolution, light yield, and energy efficiency.
• Advanced Manufacturing: Developing and implementing cutting-edge fabrication techniques (e.g., micro-fabrication, polymer, nanoparticle) to realise the designed metamaterial structures.
• Experimental Characterisation: Validating the manufactured prototypes through a range of advanced materials characterisation techniques (e.g., spectroscopy, optical and scintillation performance testing) to understand and tailor the physical and chemical interactions within these complex structures.

成人直播 is internationally renowned for its research into materials for extreme environments, offering state-of-the-art facilities and strong industrial collaborations. The project will be supervised by Dr Gregory Bizarri, an expert in radiation–matter interactions, computational modelling, and materials science, with a strong publication record (h-index 36, i10-index 69). The second supervisor is Dr. Indrat Aria, a materials scientist with expertise in low-dimensional nanomaterials and electrochemical processes (h-index 23, i10-index 43). This studentship is supported through collaboration with leading partners in precision manufacturing sectors such as the company LoadPoint Ltd.

Successful completion of this project will yield validated designs, novel manufacturing routes, and a deeper understanding of metamaterial-based radiation detectors, accelerating the development of advanced systems for ToF-PET and significantly enhancing early cancer diagnostic capabilities. The skills and knowledge gained will be highly transferable to other applications requiring high-performance radiation detection and advanced material design and fabrication. Through this multidisciplinary project, the student will develop expertise in:

• Hands-on experience with advanced computational physics and materials modelling software.
• Practical experience in advanced manufacturing techniques for novel materials.
• Opportunities to present research at international conferences and build a professional network across academia and industry.
• Uncover and quantify critical degradation mechanisms to inform the design of next-generation fusion materials.
• Translate sophisticated scientific data into impactful insights through clear communication to diverse audiences, including industry stakeholders and policymakers.
