Dr Chauraya's main field of research work lies in the development of textile antenna technology, high performance flexible, fabric electronics and optical control of electromagnetic structures used in various communication systems. Alford Chauraya has investigated the behaviour and performance of a number of microwave devices using simulation techniques and measurements. The primary goal is to demonstrate practical applications of optical illumination in antennas, filters, resonators and metamaterials.

Dr Chauraya is also a Development Engineer of Antrum Ltd, a University spinout company, set up to commercially exploit specific research projects in the Wireless Communications Research Group (WiCR) at Loughborough University. He has been involved in a project funded by European Space Agency (ESA), investigating a Development of a compact and planar textile antenna for COSPAS-SARSAT applications.

Dr Chauraya is involved with supervising several students.
