Areas of Expertise:

  • animal gut microbiology and pre-havest food safety: Studies on ecology of food-borne pathogens and commensal bacteria and their interactions with animal hosts for development of novel strategies and technology to control food-borne pathogens and reduce the prophylactic use of antibiotics in food animal production
  • detoxification of vomitoxin in feed by animal gut bacteria for swine production

Current Projects:

  • Ecological and functional genomic studies for control of clostridial infection in poultry
  • Development of biological control of bacterial pathogens in animal food production: exploring the use of bacteriophage, probiotics, and essential oils
  • Use of probiotics for control of Salmonella and other human pathogens in the production of broiler chickens
  • Essential oils as alternatives to dietary antibiotics: microencapsulation for effective delivery of the oils to pig guts
  • Identification and characterization of vomitoxin-transforming microorganisms of chicken gut and their application in detoxifying vomitoxin in swine feed
  • Development of an effective enzyme product to degrade trichothecene mycotoxins in contaminated grains
