Concordia PhD graduate wins prize for best thesis in natural sciences and engineering

July 20, 2023

Mohamed Elhattab, PhD 22 (electrical and computer engineering), has been recognized by the Quebec government for his doctoral thesis on next-generation wireless networks. 

His dissertation, titled “A Comprehensive Study of Multiple Access Techniques in 6G Networks,” was selected as the best thesis produced in the natural sciences and engineering disciplines during the 2022 academic year. 

The annual competition is administered by the Association des doyennes et des doyens des études supérieure au Québec (ADÉSAQ) and the Fonds de recherche du Québec (FRQ). The $2,500 prize recognizes doctoral theses distinguished by their “original and decisive contributions” to their respective fields.

Elhattab’s research was supervised by Chadi Assi and Ali Ghrayeb, both professors in the Gina Cody School’s Department of Electrical and Computer Engineering.

“The realization that my hard work and dedication has been recognized at such a prestigious level is truly indescribable,” says Elhattab. “It’s a validation of the countless hours my supervisors and I have invested, the numerous meetings and discussions I have engaged in, and the presentations I have delivered to elevate the quality of my work.” 

Elhattab’s thesis focused on advancing the next generation of wireless networks – “6G wireless networks.” His work centers on devising energy-efficient ways for multiple devices to connect to the network at the same time.  

By investigating several techniques that could help improve signal quality, enhance wireless signals, facilitate resource sharing among devices, and promote direct device-to-device communication, Elhattab aims to improve network performance, particularly for users at the network's fringes where signals tend to be weaker. 

In addition to its potential to enhance network performance, Elhattab's research offers solutions to reduce power consumption and promote environmental sustainability. By proposing energy-efficient strategies, his work strives to minimize the ecological impact of wireless networks. 

“We take great pride in Mohamed’s achievement in winning the prize for best thesis in the province,” says Faye Diamantoudi, dean of graduate studies. 

“This remarkable recognition highlights his significant research contributions and showcases our commitment to attracting and fostering outstanding graduate students.”
