    Research Area

    My research is in the areas of geoenvironmental and environmental engineering that are situated at the interface between environmental chemistry and biotechnology. My research programs focus on (1) fundamentally understanding physicochemical and biological processes in engineered and natural environmental systems impacted by organic and/or inorganic contaminants, and (2) developing cost-effective, environmentally sound remediation and reclamation technologies.

    *Positions are available for MSc and MEng students. Please apply to the department or contact me at wonjae.chang@usask.ca.

    Current Research Program

    1. Bioremediation in Cold Climate
      • Bioremediation at the limit: petroleum hydrocarbon biodegradation in freezing contaminated soils
      • Development of field-scale extended bioremediation systems for hydrocarbon-contaminated soils under seasonal freeze-thaw condition
    2. New Remediation Technology for Environments Impacted by Natural Resource Development
      • Remediation of soils and groundwater impacted by organic and inorganic contaminants from oil and gas production wastes
      • Bio-active natural adsorbents/biofiltration for the removal of contaminants in oil-field processed water
      • Functional gene-based, quantitative decision-making models for engineered bioremediation and natural attenuation
