Professor Xue Liu joined the School of Computer Science of McGill University in 2007 after completing his Ph.D. at the University of Illinois in Urbana-Champaign. Prof. Liu, now a Dawson Chair holder, is a rising star in the area of Cyber Physical Systems (CPS), which aims to design the new generation of time-critical and safety-critical systems where computing, communication, and the physical words are tightly coupled. His research focuses on the foundations and several important application domains of CPS, including Green IT and Smart Energies, Sensor and Actuator Networks, and Automotive CPS. Prof. Liu’s productivity is truly outstanding, with more than 200 journal and conference publications, most of them in the most selective and impactful venues in his area. His work is funded both by federal and provincial agencies, but also by several private companies. Objective measures of scientific impact place him at the very top of his generation in computer science in Canada. Despite his young age, Prof. Liu is involved in a number of activities that are rarely performed by junior researchers, including journal editorship positions, conference program chair, reviewer on several international panels, etc. He is also leading a large team of enthusiastic graduate and postdoctoral students, who, upon graduation, contribute to maintaining Canada’s edge in information technologies.
