Tariq Siddique is a participant in the Land Reclamation International Graduate School (LRIGS) program sponsored by NSERC CREATE.

Major Responsibilities / Research Interests:

  • Microbial transformations of heavy metals; their speciation in soil, sediment and water; and characterization of microbial populations involved in biotransformation processes
  • Biodegradation of petroleum hydrocarbons under anaerobic conditions; metabolic pathways of hydrocarbon degradation; and molecular fingerprinting of hydrocarbon-degrading microbial communities
  • Pore-water chemistry and clay mineralogical properties to understand mechanisms of oil sands tailings densification
