Professional Profile
🎓 Education
Oladayo earned his Ph.D. in Space Geophysics from INPE, Brazil (2019–2024), focusing on geomagnetic disturbances and their effect on the Brazilian equatorial ionosphere. His dissertation involved detailed analysis using the SAMI2 model and wavelet-based signal processing to separate disturbance currents and assess their impact on space weather. He holds a Master’s degree (M.TEC.) in Radio Propagation, Ionospheric and Space Physics from Ladoke Akintola University of Technology, Nigeria (2015–2017), and a Bachelor’s degree (B.TEC.) in Pure and Applied Physics from the same university (2005–2010). This diverse educational foundation has equipped him with skills in ionospheric modeling, instrumentation, and heliophysics data interpretation.
💼 Experience
Oladayo is a Scientific Officer at Nigeria’s National Space Research and Development Agency, analyzing ionospheric data such as TEC, magnetic fields, and ionograms. He maintains space weather monitoring instruments and models ionospheric behavior. At INPE, Brazil, he conducted Ph.D. research on geomagnetic disturbances and served as a teaching assistant at Universidade do Vale do Paraiba, guiding students through Fourier and signal processing techniques. Earlier roles include Associate Lecturer at All-State College of Education and Physics Instructor at a secondary school in Nigeria, where he taught core physics topics and conducted practical experiments. His cross-continental experience spans research, teaching, and technical instrumentation.
🔬 Research Interests
Oladayo’s research centers on space weather, with a focus on geomagnetic disturbances and their influence on the equatorial and low-latitude ionosphere, especially in Brazil. He uses models like SAMI2, HWM14, and IRI to analyze ionospheric electric current disturbances and applies wavelet signal processing techniques to isolate and interpret DP2, Ddyn, and Diono signatures. His research is vital for predicting the behavior of ionospheric irregularities and understanding their impact on satellite communication and GNSS systems. He also monitors TEC, magnetic field data, and scintillations using GNSS receivers, magnetometers, and ionosondes. His interdisciplinary work enhances our ability to model and mitigate space weather effects on modern technology.
