As a seasoned educator and researcher, I consider myself a versatile resource person whose knowledge cuts across the Physics, Electronics and Renewable Energy disciplines, spanning over three decades of experience in teaching and research. As a highly motivated individual, I am able to apply my unique versatility to bear on any related position in these fields, that correlate with my practical knowledge and experience. My career journey has been enriched by teaching both undergraduate and postgraduate courses in these fields, coupled with hands-on experience in electronic product design and deployment.
My research interests cover three primary areas: Solar Energy, Renewable Energy and Atmospheric/Ionospheric Radio Propagation Physics. These fields not only represent pressing global challenges but also offer immense potential for technological advancements through innovative instrumentation solutions. Presently, I am the principal investigator in the investigation of natural dyes extracted from local plants as photosensitizers in the fabrication of Dye-Sensitized Solar Cells (DSSCs) in the Faculty of Natural Science, Redeemer’s University, Nigeria. Our faculty's DSSC research group was awarded the Africa-UniNet grant, sponsored by the Austrian OeAD agency. This grant enabled us to visit the Linz Institute of Organic Solar Cells (LIOS) at Johannes Kepler University (JKU), Austria, where we conducted research on dye-sensitized solar cells from March to April 2024.
Apart from degrees in Physics, I also hold an MSc in Renewable Energy and the Built Environment (REBE) from the University of East London, and my work in Solar Energy and Renewable energy focuses on enhancing photovoltaic efficiency through advanced instrumentation techniques, such as real-time monitoring using IoT devices like Arduino microcontrollers. This approach not only improves operational efficiency but also contributes to data-driven decision-making in renewable energy systems. Utilizing tools like MATLAB/SIMULINK, I aim to optimize photovoltaic efficiencies of dye-sensitized solar cells by combining simulation and experimental studies.
My multidisciplinary background, coupled with a proactive approach to research and development, positions me well to make substantial contributions to any institution's mission of advancing knowledge and innovation in Physics, Renewable Energy, Instrumentation and related fields.

Tutoring Approach

My teaching/tutoring approach for A level/Undergraduate students:

 I would undertake a preliminary evaluation to identify students’ current level of knowledge of topic, i.e. do an informal assessment of students’ knowledge - discovering learning gaps.
 I would also ensure that learning goals be aligned with syllabus or course content as the case may be (e.g., A-Level Cambridge/Edexcel, or University modules).
 Begin with qualitative understanding of physical concepts before proceeding to main equations and problem solving.
 Use analogies, thought experiments (e.g. Albert Einstein’s thought experiments), and visual aids (use of visual and technological aids).
 Practice solving past examination papers to boost the students’ confidence.
 Incorporate virtual labs, simulations and animations (e.g., PhET, GeoGebra) and computational tools/plotters (e.g., Excel, Origin, MATLAB).
 Relate Physics to engineering, technology, and real world phenomena (e.g., Stopping distance of a car, thrust and lift of an air plane (Newton’s laws); Difraction, refraction and reflection of radar waves (F117 and B2 Spirit stealth aircraft), Uranium 238U enrichment for power generation.
 Have feedback on assignments.
 Use formative assessments like oral questioning, to keep track of progress.
 Encourage student reflection on what they learned, difficulties faced in grasping concepts, and how to improve.
 Critical thinking on how to tackle exam questions - knowing the kind of answer the examiner expects.
 Mentoring and motivating the students - relevance of Physics and its applications in the fields of medicine (e.g., MRI, Ultrasound), Renewable energy (Solar PVs, wind energy conversion systems).
