Research Overview:

Horizontal gene transfer (HGT) is a natural type of bacterial evolution that allows cells to transfer large pieces of DNA amongst one another. HGT is particularly common in native microbiomes, and serves as the primary way that bacteria, and especially pathogens, adapt to new and often stressful environments. Our lab uses systems and synthetic biology approaches to engineer genetic communication in bacterial communities. Specifically, we integrate computational and experimental techniques, including mathematical modeling, bioinformatics, and molecular microbiology, to understand, predict, and optimize natural HGT machinery for various purposes. This work is applicable to a broad range of clinical and environmental contexts, including inhibiting drug resistance and creating functional human or agricultural microbiome systems. Ongoing projects involve designing optimal HGT recipient strains, and engineering a toolbox of orthogonal HGT components.
