Slim Boumaiza is a Professor in the Department of Electrical and Computer Engineering at the University of Waterloo.
His research is focused on defining, conceptualizing, designing, and realizing high-performing microwave and millimeter wave circuits and systems for wireless communications (with applications in 4G, 5G and the Internet of Things). He directs the Emerging Radio System Research Group (EmRG), which conducts multidisciplinary research encompassing the semiconductor device, circuit, and system levels of radio hardware. Under his supervision, researchers investigate the areas of transistor modelling and characterization (at the semiconductor device level), ultra wideband and highly efficient power amplifiers (at the circuit level) and low power linearization schemes (at the system level).
In the above research areas, Professor Boumaiza has authored and co-authored a total of over 45 refereed journal publications, over 100 conference publications and delivered over 40 workshops/talks to members of academia and industry.
He is passionately involved in communicating knowledge of radio systems through teaching, supervision, and youth outreach. He has taught several undergraduate and graduate courses covering basics of Electrical Engineering and advanced topics in microwave engineering. Over 100 highly qualified personnel (undergraduates, masters, PhDs, postdoctorates, research staff) have worked under his supervision to date, many of whom have gone on to secure highly sought-after positions in industry. Dr. Boumaiza and his team also actively participate in university-led efforts to engage youth and minorities and promote their interest in Engineering.
