Dr. Gabriel Gonçalves Machado obtained his BSc degree in Electronic Engineering from the Federal University of Pernambuco, Brazil. He has a PhD in Electronic Engineering with focus in the area of antennas and propagation, obtained from Queen’s University Belfast (QUB), UK. His PhD was related to thin FSS based microwave absorbers for applications in ‘busy’ antenna environments and the reduction of the radar cross-sections of metal backed antennas.

In 2021, he joined as a research fellow at the Centre for Wireless Innovation (CWI), part of Queen’s University Belfast, and his research has involved: virus and microwave interaction, GNSS antenna development, microwave absorbers, and his most recent focus is on the development of millimetre wave Reconfigurable Intelligent Surfaces (RIS) for 5G and 6G communications.

He joined Ulster University in August 2023, where he teaches Embedded Systems and Sensors to MSc in IoT students. Beyond his interest in RIS development, he has a particular interest in the development of devices and practices in antennas and propagation focused towards sustainability, e-waste reduction, and energy efficiency.
