Teaching and/or Extension Activities:

Teaching activities include food microbiology and contributions to relevant lectures in food sanitation and quality, HACCP, and foodborne pathogens, and the development of an advanced graduate course in food safety microbiology. Extension and outreach program focuses on working closely with the Nebraska food industry to improve microbial safety and protect public health. Extension activities include on-site food safety assessments, workshops, and webinars to disseminate pertinent food safety information, and teach HACCP and FSMA courses.

Research Area:

My area of expertise is microbial food safety, especially the safety of foods of animal origin. My research program aims at improving food safety and protecting public health by contributing to the understanding of pathogen ecology along the farm-to-table continuum, and by helping to mitigate the risk of foodborne illness in the end consumers. Specific research interests include:

  1. The spread and routes of transmission of foodborne pathogens along the farm-to-table continuum;
  2. The design and evaluation of physical, chemical, and biological post-harvest mitigation strategies to reduce the risk of pathogen transmission; and
  3. The methodologies to better detect foodborne pathogens in multiple food and animal matrices as well as the phenotypical and genotypical characteristics that allow pathogens to survive, multiple, and even thrive in food processing environments.
