Izhar Khan, Ph.D.

Research Scientist

My research interests, in the field of Environmental Health, Biodiversity and Bioresources, are to develop rapid and simple state-of-the-art quantitative methods for rapid detection and identification of water- and foodborne human and animal pathogens for identification of sources of fecal pollution in various environmental niches. In addition, I have been working on taxonomic classification of bacteria such as genus Acinetobacter, Campylobacter and Arcobacter and study their pathogenicity and antibiotic resistance to human and animals using Next Generation Sequencing in order to provide insights into the genetic diversity and evolutionary relationship among species and strains.

Current research and/or projects

  • Impact of agricultural practices and environmental factors on the distribution and diversity of bacterial waterborne pathogens in agriculture watersheds
  • Development of state-of-art molecular tools for the rapid detection and identification of micro-aerophilic pathogens
  • Quantitative real-time PCR analysis for detection and quantification of human and animal bacterial and viral pathogens from various environmental sources
  • Molecular detection and characterization of emerging waterborne pathogens and microbial water quality indicators in agricultural and urban watersheds
  • Genotypic characterization and of pathogens by DNA sequencing, PFGE, RFLP analyses

Research and/or project statements

1. Strengthening the competitiveness and sustainability of the Canadian agriculture and agri-food sector

2. Promoting innovation and a healthy environment by focusing on following priorities to provide the best scientific information for regulatory and policy decisions:

       i).Enhance environmental performance of the Canadian agricultural system;

       ii). Improve environmental performance and sustainability of swine or dairy production systems;

       iii). Enhance the quality of food and the safety of the food system; iv) Improving the identification and understanding of crop pests and beneficial organisms;

       v) Reducing soil chemical, biological and physical degradation and maintaining soil health by improving farm and manure management practices; 

       vi). Identify the BMPs to mitigate the risk of water, soil and air contamination.
