About The Author

I focus on next-generation municipal water services (drinking water, wastewater, stormwater) framed around resource recovery (i.e. water, energy, fertilizers) for improved ecohealth and living conditions; integrated with quantitative microbial risk assessment (QMRA) to identify research gaps and management targets. Current topics include water system management (treatment performance, post-treatment control of opportunistic pathogens) from a public health perspective:

  1. Premise plumbing biofilms and environmental pathogens; identification of novel respiratory pathogens and their amoebal hosts by application of microarrays, metagenomic analysis and qPCR in collaboration with the U.S. EPA and Alberta Health.
  2. Antibiotic-resistance (resistome) gene flow within reclaimed water biofilms (qPCR and metagenomic) in hospitals.
  3. Application of QMRA to interpret the above and focus management options and regulatory reform (Health Canada).
  4. Integration of human health with ecosystem/LCA and economic analyses to identify more sustainable municipal water services; working with and to inform private and government housing developers.

Free-Living Amoebae – A Novel Waterborne Risk Pathway That Now Includes Enteric Viruses

When it comes to waterborne pathogens and host-specific pathogens like human enteric viruses, it is easy to assume that they evolved through human interactions. Yet as we now recognize various humans pathogens from parasitic protozoa (Toxoplasma gondii), through environmental bacteria (Vibrio cholerae and Legionella pneumophila) to giant viruses (Mimivirus), free-living amoebae (FLA) are probably the
