Felix Olise, PhD is a Professor of Nuclear Physics at Obafemi Awolowo University (OAU), Nigeria, with a distinguished career spanning nuclear science, reactor physics, and advanced materials characterisation. He holds a B.Sc. in Engineering Physics (Materials Science) and a Ph.D. in Nuclear Engineering Science and has extensive experience in both nuclear reactor applications and accelerator-based analytical techniques.

He is widely recognised for pioneering the application of nuclear analytical methods in Nigeria, particularly in the use of Particle-Induced X-ray Emission (PIXE) and Total Reflection X-ray Fluorescence (TXRF) for environmental and materials analysis. His research has significantly advanced the understanding of trace element distribution, heavy metal contamination, and radiological impacts on environmental and public health systems.

In addition to experimental expertise, Prof. Olise has made important contributions to nuclear reaction modelling, including cross-section calculations and pre-equilibrium reaction mechanisms, which are fundamental to reactor physics, nuclear data evaluation, and materials performance under irradiation. This combination of experimental and theoretical competence positions his work at the interface of nuclear science and applied energy systems.

He has benefited from and contributed to several international research programmes supported by the International Atomic Energy Agency (IAEA), TWAS-UNESCO, and TETFund, with research engagements in leading laboratories across Brazil, Portugal, the United Kingdom, and South Africa (including iThemba LABS). He has authored over 50 peer-reviewed publications and maintains active collaborations within the global nuclear science community.

As Head of the Department of Physics and Engineering Physics, he provides academic leadership in teaching and research, supervising undergraduate and postgraduate work in nuclear science, reactor physics, and materials. His work continues to bridge fundamental nuclear physics with practical applications in energy, environment, and technological development.

Prof. Olise’s research interests are centred on nuclear science, materials physics, and environmental sustainability, with a strong emphasis on both experimental and theoretical approaches. His work includes the development and application of accelerator-based analytical techniques such as PIXE and XRF for high-resolution elemental characterisation of environmental and engineered materials.

A major component of his research focuses on nuclear reaction modelling, particularly the calculation of nuclear cross sections and pre-equilibrium reaction processes, which are essential for reactor design, nuclear data libraries, radiation shielding, and materials performance assessment in nuclear environments. His interests also extend to radiation–matter interactions, including the behaviour and degradation of nuclear materials under irradiation.

He is actively engaged in environmental radioactivity studies, radiological risk assessment, and the application of nuclear techniques to pollution monitoring and source apportionment. His research integrates experimental measurements with computational modelling and statistical analysis to address complex problems in environmental and nuclear systems.

Current research directions include advanced nuclear materials for energy applications, reactor-and accelerator-relevant cross-section data generation, and the use of nuclear analytical techniques to support sustainable environmental management and policy development.
