Timothy A. Johnson's research centers on the gut microbiome of livestock and other animals, examining how diet, antibiotics, and environmental exposures shape gut bacterial communities and influence animal health, growth, and behavior. A major recurring focus is antibiotic resistance genes (the 'resistome') in agricultural and environmental settings, studied through a One Health lens connecting human, animal, and environmental microbial ecosystems. Note that some listed publications (on cardiac catheter procedures) appear unrelated to this core body of work and may reflect a data mixing issue rather than this PI's actual research.
