Professor Helaoui received the MSc and PhD degrees in communications and information technology from École Supérieure des Communications de Tunis, Tunisia, in 2003 and 2006, respectively, and the PhD degree in electrical engineering from the University of Calgary in 2009. His research activities are funded by over $3 million over the last 10 years. These funds were provided by federal and provincial funding agencies (NSERC and AITF) and industrial collaborators such as the Canadian Space Agency, Ericsson Canada, Norsat International, Nanowave Technologies, the National Research Counsil of Canada,and CMC microsystems. He supervised over 50 graduate and undergraduate students and over 10 postdoctoral fellows.
His teams' research activities have led to over 150 publications, 1 book, 3 book chapters, and 11 patents. Many of his research publications are highly cited with a total of over 2300 citations, which resulted in h-index of 26 and a g-index of 46.
