Dr. Byron Chaves

Assistant Professor
272 Food Innovation Center
Lincoln, NE 68588-6205

I enjoy visiting food facilities, interacting with processors, and helping Nebraskan produce safer, high quality foods.

Faculty Profile


  • BS (Licenciatura) in Food Technology, University of Costa Rica
  • MS in Food Science/Experimental Statistics, Clemson University
  • Visiting Research Scientist, Centre for Food Safety at University College Dublin (Dublin, Ireland) and Food Safety Laboratories at ANSES (Maisons-Alfort, France)
  • PhD Food Safety/Microbiology, Texas Tech University
  • Postdoc – Food Microbiology, Texas Tech University

Teaching and/or Extension Activities

  • My extension program focuses on providing training and technical assistance to the Nebraska and regional food manufacturing industry. Activities include on-site food safety assessments for compliance with federal food safety regulations; development of environmental monitoring programs for pathogens; assisting with the development of HACCP and food safety plans; offering workshops and webinars to disseminate relevant food safety information; and teaching GMPs, HACCP and FSMA rule courses. Additionally, I am the State Lead for the North Central Region FSMA Center, leading efforts for the successful implementation of FDA food safety regulations across Nebraska. I enjoy visiting food facilities, interacting with processors, and helping Nebraskan produce safer, high quality foods.
