Siti Fairus Abdul Sani is an Associate Professor at Universiti Malaya (UM), specialising in Radiation and Medical Physics. She obtained her PhD from the University of Surrey, United Kingdom, in 2015 and was honoured with the prestigious Anugerah Saintis Muda Negara 2024 (National Young Scientist Award) in recognition of her contributions to scientific research and innovation. With 151 publications, an H-index of 22, and over 1,600 citations, she has established a strong academic and research record. Her interdisciplinary research spans medical, industrial, environmental, agricultural, and nuclear applications, with a focus on radiation dosimetry, biophysics, radiation-modifying agents, advanced shielding materials, and applied nuclear technologies. Her contributions include clinical and retrospective dosimetry using innovative materials and optical techniques; biophysical characterisation of metabolites associated with EMT, FDFT1, endometrial diseases, and amyloidosis; development of radiosensitisers and diagnostic contrast agents; radionuclide assessment; and Monte Carlo simulations for medical and nuclear applications. A notable research highlight is her work on rare-earth-based radiation-shielding materials for space applications, published in Physics Reports (Impact Factor: 27.5), a journal ranked among the top 10% in its WOS category. Her research further integrates artificial intelligence (AI), the Internet of Things (IoT), and drone-assisted technologies for environmental radiation monitoring, alongside investigations into radiation safety, nuclear waste management, and agricultural applications. Collectively, her work seeks to advance innovative, safe, and sustainable radiation technologies
