Welcome to Dr. Kwangcheol Casey Jeong's Lab at the University of Florida!

Antimicrobial Resistance Seminar for the Feed the Future Innovation Lab for Livestock Systems, USAID 

Dr. Jeong's Lab Members 

Goals
  • Our research goals are to provide solutions for animal and human health by understanding host-pathogen interactions at the molecular level. 
  • We develop methods to prevent and cure diseases caused by pathogens.
