Tongyuan Wang, PhD, M.Sc., M.E., M.A., has studied and worked in multiple fields. He got his first degree in civil engineering and a Master's in engineering management, both from Chongqing University, China, in the 1980s. He then worked at that university as a lecturer and as an economist in a provincial urban development company. Upon becoming a vice professor, he moved to Canada, where he obtained an M.A. in economics first. Then, he switched to computer science and pursued a Graduate Diploma, a Master's, and a PhD, all from Concordia University, by 2010. After graduation, he did not continue his teaching career due to a convention that a new PhD holder may start as an assistant professor regardless of previous work experience. Instead, he has been working for a startup company to date. During the course, he continues academic and industrial research. His main research interests include pattern mining, ecological and smart cities, as well as sustainable development. In pattern mining, his recently published work has been evaluated by Altmetric as “the 1st percentile (ranked 1st) of the 1 tracked articles of a similar age in International Journal of Data Science and Analytics.” In sustainable development, his published work has been evaluated with new paper invitations and presentations at dozens of international academic journals and conferences.
