My main areas of research interest are the design and development of new and novel methods of radio frequency power amplification. These methods are intended to provide the required levels of linearity to support a wide range of standards and also to be efficient enough to reduce significantly the power consumption of radio networks and can also to be used in mobile applications where power consumption is required to be kept to a minimum. Current research is looking at new and novel methods of designing multimode amplifier linearisation systems which are capable of linearly transmitting multiple standards with minimum power consumption.
