Research Interests

My research interests are in microbial safety of water and pre-harvest foods with emphasis on zoonotic foodborne and waterborne pathogens. The microbial organisms I have been working on include protozoa (Cryptosporidium, Giardia), indicator bacteria (E. coli, Enterococcus), pathogenic bacteria (E. coli O157, Salmonella enterica), and fungi (Enterocytozoon bieneusi, Encephalitozoon intestinalis). Goals of my research are to protecting the safety of water and pre-harvest foods through developing strategies against microbial infection and contamination. My specific interests are:

  • Development and validation of methods for detection of microbial pathogens from water, animal, plant, and environmental samples;
  • Fingerprinting of bacteria by pulsed field gel electrophori (PFGE) and protozoa by genotyping and BLAST;
  • Monitoring the occurrence and movement of antibiotic resistant bacteria in pre-harvest environment;
  • Evaluating of viability, infectivity, and survival of pathogens using in vitro and in vivo methods.
