Assistant Professor Department of Electrical Engineering College of Engineering

I obtained my Bachelor's degree in electrical engineering from King Saud University in 2010. After completing my undergraduate degree, I pursued a Master of Science degree in communication engineering from King Saud University in 2016. Most recently, I earned my PhD in wireless communications from the University of Warwick School of Engineering.

My research interests include the design, modelling, and performance analysis of wireless communication systems, particularly those related to energy-harvesting communications and visible light communication/radio frequency (VLC/RF) systems. I am also interested in developing green communication systems and networks and using mathematical optimization techniques to address problems in wireless communications. My background in stochastic processes and stochastic geometry also informs my work on wireless networks.
