It is with great sadness that we report the passing of Prof. Emeritus A.R. (Roy) Boothroyd, the founding Chair of the Department of Electronics. Under his guidance the Department came to be internationally recognized for excellence in research and teaching in microelectronics and solid state device technology. Prof. Boothroyd strongly believed that the work of the Department should be relevant to the needs of the community it served. He collaborated closely with the Canadian microelectronics industry, frequently facilitating opportunities for graduate students to carry out leading-edge research with local companies. His own research dealt primarily with fast and accurate modelling of the transistors in CMOS integrated circuits. His expertise in this field was instrumental in bringing the Canadian telecom industry to a position of global leadership. For this work he was elected a Life Fellow of the Institute of Electrical and Electronic Engineers. Within the Department he built a vibrant laboratory for experimental research on solid-state device physics and technology. He helped develop an undergraduate curriculum that prepared students for careers in innovation at the state-of-the-art in microelectronics. He will be greatly missed by his colleagues in academia and industry, and by generations of undergraduate and graduate students.
