Our lab uses pathogen genomics to investigate the emergence and spread of bacterial infectious diseases, with a specific interest in antibiotic-resistant pathogens that are frequent causes of healthcare-associated infections. To accomplish this, we use a variety of tools including epidemiology, bioinformatics, computational biology, population genomics, and phylogenetics. Our goal is to understand the factors that contribute to pathogen success and to develop new genomic epidemiological methods to detect, monitor, and combat the growing threat of antimicrobial resistance.
Primary pathogens of interest include Streptococcus pneumoniae, a leading cause of infections in children and adults, as well as methicillin-resistant Staphylococcus aureus (MRSA), a prevalent cause of both community and healthcare-associated infections. Other pathogens of interest include Vibrio cholerae, Neisseria meningitidis, and the ESKAPE bacteria that are commonly associated with antimicrobial resistance.
