How locally available materials can be transformed into effective solutions for radiation protection, environmental safety, and sustainable development is one important question that lies at the centre of Dr. Rilwanβs scientific journey.
Dr. Usman Rilwan is a medical and radiation physicist whose career reflects a strong commitment to research, teaching, mentorship, and the practical application of science. He earned his Bachelor of Science degree in Physics and Master of Science degree in Radiation and Medical Physics from Nasarawa State University, Keffi. He later obtained a Doctor of Philosophy in Medical Physics from Abubakar Tafawa Balewa University, Bauchi. He currently serves as a Senior Scientific Officer at the Federal University Teaching Hospital, Lafia, Nasarawa State.
His research focuses on radiation shielding, medical physics, environmental radioactivity, radiological risk assessment, and the development of sustainable protective materials. A major part of his work explores how agricultural waste, natural resources, and industrial by-products can be converted into high-performance materials for radiation protection.
Through studies involving coconut shell ash, palm nutshell ash, peanut shell ash, waste glass, bone, barite, granite waste, and other locally sourced materials, Dr. Rilwan investigates practical ways of improving the shielding, thermal, structural, and mechanical properties of concrete, glass, bricks, and related composites. His work demonstrates that materials often treated as waste can become valuable scientific resources when examined through innovation and careful research.
The mission behind his work is clear: to contribute to safer healthcare, research, industrial, and environmental practices through affordable and sustainable radiation-protection solutions. His research also supports waste reduction and promotes the use of local resources in addressing important national and global scientific challenges.
Dr. Rilwan has authored and co-authored numerous scholarly publications in reputable Scopus- and Web of Science-indexed journals, including the Journal of the Nigerian Society of Physical Sciences. His research profile includes 40 Scopus-indexed documents with 659 citations and 29 Web of Science-indexed documents with 553 citations. His broader scholarly influence is also reflected on Google Scholar, where he has 144 publications and 1,466 citations, and on ResearchGate, where he has 140 research outputs and 1,381 citations.
These figures reflect the visibility, consistency, and growing influence of his work across radiation physics, materials science, environmental safety, and related fields. They also show how his research continues to support further scientific inquiry and collaboration.
One of the major recognitions of his academic journey is the Nigerian Institute of Physics Best Ph.D. Thesis Award in 2026. This distinction highlights the quality, originality, and relevance of his doctoral research and confirms his growing contribution to the advancement of physics in Nigeria.
Beyond publications and awards, Dr. Rilwan is deeply committed to teaching and mentorship. He has taught courses across several areas of physics and supervised undergraduate research projects on radiation shielding and sustainable materials. Some of these projects have developed into publications in internationally indexed journals, demonstrating his ability to guide young researchers from scientific curiosity to meaningful research outcomes.
His personal motto is:
βI am a lifetime student, and I always stand to be corrected.β
This statement captures his humility, openness to learning, and belief that scientific progress depends on continuous improvement, critical reflection, and a willingness to accept new evidence.
Outside his professional responsibilities, Dr. Rilwan enjoys reciting the Qurβan, travelling, watching football, and spending quality time caring for his beautiful wife and children. These interests reflect the balance he maintains between scholarship, faith, family, and personal development.
Looking ahead, his long-term scientific dream is to advance radiation physics by developing sustainable, high-performance shielding materials from local resources. He also hopes to mentor future scientists and translate research findings into practical healthcare and environmental solutions that improve safety, inspire innovation, and contribute to national development in Nigeria and beyond.
The Nigerian Society of Physical Sciences proudly celebrates Dr. Usman Rilwan for his contributions to radiation physics, medical physics, sustainable materials development, environmental protection, scientific publishing, and mentorship.
His journey shows that impactful science can begin by recognising the hidden value in local resources and transforming them into solutions with national and global relevance.
