What we study
The lab studies bacteria like E. coli and Salmonella, focusing on their resistance to antibiotics and how they cause diseases in animals. They develop vaccines and research new ways to fight infections.

Current projects
Avian Pathogenic E. coli-Vectored Vaccine for Broad-Range Protection from Infectious Coryza

Characterizing the Zoonotic Potential of Canine Uropathogenic Escherichia coli (UPEC) in Urinary Tract Infections
The lab studies antibiotic‑resistant E. coli from dogs that cause urinary tract infections. Students will test how many strains resist common antibiotics, check for four virulence genes, and run a biofilm test to see if the bacteria can survive in human urine, highlighting risks of dog‑to‑human transmission.
