CAREER ACCOMPLISHMENTS AND HIGHLIGHTS
Tutored and trained several generations of Physics graduates, who are now
employed in several spheres of life, including the Medical field, Engineering,
Research and the Academia.
Co-authored several published research findings in journals of Physics and
Space Science.
Assisted in the setting up of two high standard Research laboratories in the
University of Ilorin, Nigeria:

Surface radiation flux measurements using solar trackers with pyrgeometers,
pyranometers, pressure, temperature, humidity and wind speed sensors. The
station was set up in collaboration with the university of Maryland, USA, in
1992, to provide material for Satellite Radiometric and Climatic models. The
research was initiated by The World Climate Research Programme (WCRP),
WMO, and operated by the radiometric network known as Baseline Surface
Radiation Network (BSRN), supported under NASA EOS validation grant of the
University of Maryland, USA. I was one of those responsible for the operation
and maintenance of the instruments, as well as data acquisition and archiving.

Ionospheric lab with an IPS-42 Sounder and digital Ionosonde (DBD) for
Ionospheric/Communication research. This research was initiated in 1999, by the
Aeronomy and Radiopropagation laboratory at the Abdus Salam International
Centre for Theoretical Physics, (ICTP), Trieste, Italy. The main aim was to
acquire long term ionospheric data from a tropical
region in order to validate the IRI model.
 Established and successfully ran a Private Micro Cottage industry for the
installation and management of Solar PV systems on commercial basis, and local
construction of power inverters, uninterrupted power supply (UPS) systems and
Charge Controllers.
 Established a meteorological weather station in the Department of
Physics,
Covenant University in 2012 using the Davis Vantage Pro2
instrument. Data
is logged every minute.
