Research Interests

Research in the LeJeune lab is primarily focused on understanding the ecological mechanisms and epidemiological patterns associated with the transmission of zoonotic bacteria between animal and human populations, with special emphasis on Shigatoxin producing E.coli (STEC) and antimicrobial resistant organisms. This work will lead to the discovery of strategies to prevent transmission of pathogens between reservoir species and water, wildlife, and edible crops.
