Research

After gaining degrees in Physics, I worked as a programmer for the Meteorological Office and National Grid.  I joined the School of Engineering as a post-doc in 2002 and became a lecturer in Communications Engineering in 2005.

I have worked on observations and modelling of propagation in the ionospheric since 2005 and this work continues up to the present day and has led to applications in aircraft communications and over-the-horizon radar.  I have also studied propagation of VHF and UHF signals in the troposphere through long-term measurement campaigns in the British Channel Islands in order to establish statistics for the probability of anomalous propagation in coastal areas. This work was sponsored by Ofcom and submitted to the International Telecommunications Union (ITU) to aid the planning and operation of broadcast media and mobile communications.

In more recent work, I have recently researched and supervised PhD students in the areas of MIMO for HF signals, ad-hoc wireless networks and vehicular communications.
