Research Interest

Our laboratory focuses on Lactobacillus sp, a human commensal of the gastrointestinal and vaginal tract. We are working to define how Lactobacilli communicate and respond as a bacterial community. Our long term goals are to determine the effects of this communication for host cells. Our projects include characterizing quorum sensing pathways, identifying cellular and environmental signals, and discovery of quorum sensing effects in cells.

Research

Our laboratory focus is on microbial genetics, molecular biology, and phage biology. Our primary goals are to study how bacteria such as the human pathogen Streptococcus pyogenes and the human commensal Lactobacillus acidophilus communicate through the process of quorum sensing and may be affected by external cues. A secondary goal is to study infection cycles of soil bacteriophages and what variables affect their growth.

Students may be able to work on in-person projects related to small molecule effects on S. pyogenes or L. acidophilus quorum sensing, S. pyogenes protein to quorum sensing peptide interactions, and/or phage growth analysis and archiving.
