Engr. Prof. Henry Ohiani Ohize, PhD is a Professor of Electrical and Electronics Engineering, academic leader, researcher, and author at the Confluence University of Science and Technology (CUSTECH), Osara, Kogi State, Nigeria, where he serves as the Dean of the Faculty of Engineering.

He obtained his PhD in Electrical Engineering from the University of Cape Town, South Africa, in 2017, following a B.Eng. in Electrical and Electronics Engineering from Abubakar Tafawa Balewa University, Bauchi, and an M.Eng. in Telecommunications Engineering from the Federal University of Technology, Minna. With over 18 years of teaching, research, and academic experience across universities in Nigeria and South Africa, Professor Ohize is committed to advancing engineering education, interdisciplinary research, and technology-driven solutions to societal challenges.

His research interests span artificial intelligence, wireless communications, embedded systems, the Internet of Things (IoT), blockchain technology, secure electronic voting, digital health, and AI-enabled infectious disease surveillance. His recent work increasingly explores the application of artificial intelligence and data-driven approaches to public health challenges, particularly the prediction, surveillance, and control of Lassa fever and cholera.

Professor Ohize has contributed to research and innovation through competitive research grants, peer-reviewed scholarly publications, postgraduate supervision, and multidisciplinary collaborations. He is also a member of a National high-level delegation involved in setting the research agenda for cholera, reflecting his commitment to translating engineering and computational research into practical public health interventions.

He serves as the General Chair of SAFER-TEA 2026, the 4th EAI International Conference on Safe, Secure, Ethical, Responsible Technologies and Emerging Applications, hosted by CUSTECH, Osara, from 8–10 December 2026. The conference brings together researchers, academics, industry professionals, and other stakeholders to advance responsible technological innovation across artificial intelligence, digital health, cybersecurity, energy, agriculture, and emerging applications.

Beyond research and academic leadership, Professor Ohize is passionate about making engineering knowledge accessible through effective teaching, practical learning, and innovative educational resources.

He is the author of Electronics: Principles, Concepts and Practices, a comprehensive textbook that adopts a bottom-up approach to electronics education, progressing from semiconductor fundamentals and electronic devices to circuit analysis and design. By integrating theory with practical simulations using MATLAB and LTSpice, alongside supplementary lecture slides and online learning resources, the book bridges the gap between fundamental concepts and engineering practice.

Through his teaching, research, leadership, and authorship, Professor Ohize continues to promote engineering excellence, interdisciplinary collaboration, and the application of technology to real-world problems.

Electronics: Principles, Concepts and Practices

With LTSpice and MATLAB. Sponsored by TETFund.

The field of Electronics already has numerous textbooks, prompting the question of why another one is necessary. In reality, authors often write books because they identify gaps in existing works and believe they can present the content in a more effective manner. This book is a response to such a need. It offers a unique approach to conveying Electronics concepts with hands-on tasks through circuit simulations, setting it apart from other textbooks in terms of content and presentation style.

The book follows a bottom-up approach to teaching Electronics, beginning with an introduction to semiconductor physics, followed by semiconductor devices and modeling, circuit analysis, circuit design with semiconductor devices, and concluding with an introduction to trends in Electronics. It is divided into four parts: Part I, Part II, Part III, and Part IV. The fundamental idea behind this book is to address a wide range of topics in a simplified manner, emphasizing the interactions between physics, devices, and circuits in modern Electronics. In addition, free lecture slides are made available for download.

This book intentionally avoids delving into unnecessary theoretical baggage. Instead, it focuses on building the fundamental concepts required for a thorough understanding of circuits, introducing only the necessary basic mathematical concepts. This approach makes the book highly suitable for introductory-level teaching of Electronics in all institutions.

The text integrates LTSpice and MATLAB into the course syllabus for Electronics, allowing for self-directed learning and reaping the benefits of learning through mistakes. Simulation tasks are included at the end of each part to reinforce the concepts learned in preceding chapters. These tasks are designed to challenge students without trivializing the development or application of intuition, which is crucial for an engineering career. Students are encouraged to explore "what-if" scenarios in the simulation tasks, while graphical outputs further enhance their understanding of mathematical derivations and assumptions.

In conclusion, this book fills the gaps identified in existing Electronics textbooks by offering a unique approach that utilizes circuit simulations. Its structure, emphasis on fundamentals, and integration of simulation tools make it a valuable resource for introductory-level teaching. By focusing on practical comprehension and providing opportunities for self-directed learning, this book aims to equip students with a solid foundation in Electronics.
