    Visiting Scholars/ Research Assistants Supervision

    As the Scientific Director of the Multimedia Research Centre, one major responsibility is to supervise and train highly qualified personnel (HQP), including graduates and undergraduates as well as research assistants and visiting scholars. Since 2006, I have supervised or co-supervised over forty HQP. Most of them worked as researchers for the CROME Online/Mobile Multimedia Education Project and a number have since joined industries including City of Edmonton, Aptina (San Jose), Pixelstorms Entertainment Studios (Los Angeles), Bioware (Edmonton), Microsoft (Redmond), SAS (North Carolina), Sols Systems (New York), Octagon Research (Pennsylvania) GREE International (Vancouver), Orion Health (Edmonton) and Smart Technology (Calgary). I have also supervised five visiting scholars from China, Brazil and Mexico in 2013-2014. Another two scholars came from Mexico in September 2014 and Feb 2015 respectively.
