Dr. J. Q. Shang - Research Interests


RESEARCH INTERESTS

 

Electrokinetics in geotechnical and environmental engineering applications. Dr. Shang has carried out research in this field in collaboration with industries and academics worldwide. She was granted two fellowships and visited the University of Western Australia and the University of Melbourne in 2003 and 2009, respectively. She has collaborated with companies and organizations on electrokinetic treatment of industrial wastewater, mine tailings and river sediment, including Chrysler Corp, Polycon Industries, Golder PasteTec, Cameco Corp, and Upper Thames River Conservation Authority.  Her research has received funding from NSERC CRD, Ontario Centres of Excellence and industries.

Subsurface contamination monitoring and detection using electromagnetic waves. This research is highly exploratory in nature. She has developed a measurement device for complex permittivity of soils. The complex permittivity data are analyzed using artificial neural networks in an effort to quantitatively identify type and scale of contamination.  The work has resulted in extensive publications and was presented at international conferences and invited workshops. The research was supported by NSERC CRD with cash and in-kind contributions of geotechnical consulting companies (Golder Associates and AMEC).

Utilization of coal fly ash in management of reactive mine tailings. The ongoing collaborative research is being carried out as a joint effort of her research team, Ontario Power Generation and Goldcorp Musselwhite Mine. The research is targeted on using coal fly ash to prevent generation of acid mine drainage from reactive mine tailings. The work included lab study and a field trial on the Musselwhite mine site. Currently she is analyzing field test data from past four years. It is hoped that the outcome of this research would lead to an energy saving and environmentally friendly approach for on-land disposal of reactive mine tailings.
