I am interested in environmentally dependent regulation of bacterial gene expression and survival mechanisms of tuberculosis bacilli. I am specifically focused on the problem of persistence, the ability of small populations of tuberculosis bacilli to survive antibiotic treatment despite lacking alleles that code for genotypic drug resistance. The phenomenon of persistence may be the basis of the need for lengthy treatment regimens to cure tuberculosis and could also contribute the ability of the bacteria to establish a latent infection. I have characterized the transcriptome of tuberculosis persister cells to identify genes that may be involved in the phenomenon, and have created mutant strains defective for persistence. I am in the process of characterizing these mutants using mouse models and various -omics technologies and work collaboratively on other projects that require systems biological approaches.
