Dr Hamed A. Alshammari, PhD, MSc, MInstP, is an Assistant Professor and Chairman of the Department of Radiological Sciences at the College of Applied Medical Sciences, Imam Abdulrahman Bin Faisal University (IAU), Saudi Arabia. He also serves as a Consultant in Medical Physics at King Fahd Hospital of the University.

He obtained his PhD from the University of Liverpool, United Kingdom, where his doctoral research focused on semiconductor Compton camera technology for prompt gamma imaging in proton therapy. He holds an MSc in Radiation and Environmental Protection from the University of Surrey, United Kingdom, and a BSc in Radiological Sciences from the University of Dammam, Saudi Arabia.

His academic and research expertise encompasses medical physics, radiation dosimetry, radiation protection, nuclear radiation detection, Monte Carlo simulations, medical imaging, and environmental radioactivity. His research interests include advanced radiation detection technologies, computational radiation transport, radiation dose optimisation, and the application of nuclear science and technology in healthcare.

In addition to his research activities, Dr Alshammari is actively engaged in undergraduate and postgraduate teaching, research supervision, curriculum development, academic quality assurance, and strategic planning. His academic leadership focuses on advancing radiological sciences education, strengthening research collaboration, and aligning academic programmes with developments in healthcare technology and professional practice.

My research interests lie at the intersection of medical physics, nuclear radiation detection, radiation dosimetry, and computational modelling, with particular emphasis on the development and application of advanced radiation technologies in healthcare.
The principal areas of interest include:
•    Medical Physics and Radiation Dosimetry: Radiation dose assessment, patient dosimetry, radiation protection, and optimisation of medical imaging procedures.
•    Proton Therapy and Prompt Gamma Imaging: Advanced radiation detection technologies, semiconductor Compton cameras, and prompt gamma imaging for particle therapy applications.
•    Monte Carlo Simulations and Computational Medical Physics: Radiation transport modelling, computational human phantoms, dose conversion coefficients, and simulation-based dosimetry.
•    Diagnostic Imaging and Radiation Dose Optimisation: Computed tomography (CT), diagnostic reference levels (DRLs), patient radiation safety, and quality assurance in medical imaging.
•    Environmental Radioactivity and Radiation Protection: Naturally occurring radioactive materials (NORM), gamma-ray spectrometry, environmental radiation monitoring, and radiological hazard assessment.
•    Nuclear Radiation Detection and Instrumentation: Semiconductor radiation detectors, gamma-ray spectroscopy, nuclear instrumentation, and radiation measurement techniques.
My research aims to contribute to improvements in radiation measurement, medical imaging, treatment verification, and radiation safety through experimental investigations, computational methods, and interdisciplinary collaboration.

Dr Alshammari contributes to undergraduate and postgraduate education in radiological sciences, with teaching expertise in medical physics, radiation protection, diagnostic imaging physics, and research methodology.
His teaching activities include:
•    Physics of Radiology
•    Research Methodology
•    Radiation Metrology
•    Radiation Dosimetry and Radiation Protection
•    Environmental health physics
•    Research Project Supervision
He is actively involved in supervising undergraduate and postgraduate research projects covering radiation dose optimisation, diagnostic imaging, medical physics, and radiation protection.
