Research interests:

Chronic infections place a significant burden on healthcare systems, requiring over $20 billion in treatment annually in the United States alone. Notably, chronic infections are frequently polymicrobial and are often recalcitrant to antibiotic treatment. Despite this clinical importance, many key features of bacterial physiology in chronic infections, including the molecular mechanisms and impacts of microbe-microbe interactions, remain understudied. My research interests center around understanding bacterial physiology and behavior in situ during human infection, with a focus on elucidating the mechanistic links between co-infecting microbes and disease severity. Work in my lab is at the cutting edge of assessing bacterial physiology in human infection and leverages classic microbiological techniques in combination with -omics approaches to ask foundational questions about how the prominent pathogen, Staphylococcus aureus, causes disease and persists in human infection. Central questions in my lab are:

1)    What mechanisms allow S. aureus to establish and persist in chronic infection?
2)    How do other community members impact S. aureus physiology in polymicrobial infection?
3)    What is the role of spatial structure in mediating interactions between microbes in chronic infection?

To address these questions, our research uses next-generation sequencing, microscopy, computational pipelines, deep learning approaches, and microbial genetics.
