Research Interests 

My general research interests are in the areas of biological processes in engineered and natural environmental systems, particularly in the areas of biofilm processes and microsensor techniques. I have studied biofilm processes in wastewater treatment, in drinking water distribution system, in river sediment, and in oil sands tailing water. My study of microsensor techniques includes oxygen, pH, redox potential, cholrine, monochloramine, ammonium, nitrite, sulfide, hydrogen sulfide, sulfate, methane microsenors.

Working with my graduate students, we built the Microsensor Laboratory for Environmental Biofilm Studies, supported by a CFI New Opportunities grant and an NSERC grant. It is the first-of-its-kind in Canada. By using the apparatuses in this laboratory, we have mapped the three-dimensional distribution of oxygen in biofilms.

Research Currently in Progress

My current research focuses on three areas:

  1. Biological processes in water and wastewater treatment
  2. Development and application of microsensor techniques for environmental applications
  3. Oil sands tailings water treatment using biological processes
