Dr. Abdulrazak Otaru earned his Ph.D. from the University of Nottingham, UK, in December 2018. His doctoral research specialized in the integration of three-dimensional advanced imaging and numerical simulation to optimize bottleneck microporous structures for acoustic absorption. Following his doctoral studies, he resumed his academic tenure at the Federal University of Technology Minna, Nigeria, within the Department of Chemical Engineering. In 2023, Dr. Otaru joined the Department of Chemical Engineering at King Faisal University, Al Ahsa, Saudi Arabia, where he was elevated to the rank of Associate Professor in February 2025. His academic contributions include extensive teaching and project supervision at both undergraduate and postgraduate levels, along with community engagement and administration. Dr. Otaru’s research is widely published in high-impact ISI journals, focusing on Modelling, Simulation, and Intelligent Systems. His technical expertise encompasses Computational Fluid Dynamics (CFD), Machine/Deep Learning Applications, Multiscale Modelling, and Advanced Imaging. His work addresses critical challenges in chemical processing, thermal systems analysis, energy conservation and management, biomass/polymer science, acoustic attenuation, and environmental engineering.
