Brief Bio

My undergraduate degree was in electronic and communication engineering. After obtaining a master’s degree in Avionic systems from the University of Sheffield. I diverged to attain a PhD degree in bio-impedance analysis; a cost-effective yet accurate method to estimate human body-composition. This was from Aston University, Birmingham.

My first job was as a research assistant at the Institute of Neuroscience in Newcastle University and involved working with miniature electronics to monitor primate motor activity. This was followed by a year-long position as research associate in the Engineering Tomography Lab at the University of Bath. The work here focused on developing a near real-time magnetic induction tomography system. After an 18-month job as a sensor engineer at Dyson technologies Ltd, I started to work as a Research Fellow in the SERENE group at the University of Birmingham in 2016.

Current Project

At SERENE my work has primarily focused on understanding the effect of equatorial ionospheric scintillation on wideband UHF signals. UHF signals from geo-stationary satellites are analysed to estimate the ionospheric impulse response. This allows statistical characterisation of amplitude and phase variations in the transmitted signal due to scintillation. Such information is valuable to modem designers developing high-capacity (wideband) trans-ionospheric communication systems at UHF.
