About

Qing Zhao received her BSc degree in control engineering from Northeastern University (NEU), Shenyang, P. R. China, and the Ph.D. degree in Electrical and Computer Engineering from the University of Western Ontario (Currently known as Western University), London, Ontario, Canada, in July 1993 and October 1999, respectively. Since September 2000, she has been with the Dept. of Electrical & Computer Engineering, Univ. of Alberta, Edmonton, Canada, where she is currently a professor. During her first sabbatical leave from Aug. 2008 to Sept. 2009, Dr. Zhao had visited two institutes in Europe. Awarded an international scholar grant, she had been a visiting professor at Université Libre de Bruxelles, Brussels, Belgium, from Aug. 2008 to Dec. 2008. She was also awarded the Alexander von Humboldt Fellowship for Experienced Researchers in 2009 and had been a visiting professor at Univ. of Duisburg-Essen, Duisburg, Germany from Jan. to June 2009. While she was on her second sabbatical leave, from Nov. 2019 to Jan. 2020, she had been a visiting professor at NEU, China. She has been a member of IEEE, AIAA, ISA and she is a registered professional engineer in Canada. She has served on several technical and professional committees. She is currently a member-at-large of the Canadian Engineering Qualification Board (CEQB) serving the Syllabus Committee and the Admission Committee; a member of the Board of Examiner for Association of Professional Engineers and Geoscientists of Alberta (APEGA), Canada; an international committee member of China Automation Association (CAA) Technical Committee on Fault Diagnosis and Safety of Technical Processes. She was a panel member of the Strategic Grant Selection Panel of the Natural Sciences and Engineering Research Council (NSERC) of Canada.
