Research Interests
    Current research activities of my laboratory center on the application of molecular evolutionary biology principles and techniques to issues of epidemiology and comparative genomics within various groups of bacterial pathogens. More specifically, we are interested in such things as the relative role of lateral gene transfer versus positive selection in the adaptation of various pathogens to their environment, both at the species and strain level. This work involves the acquisition of comparative genome sequence data using the latest genome sequencing technology, concomitant with evolutionary bioinformatic analysis of the resulting data. It also entails using the information arising from the evolutionary analyses to perform gene knockout and site specific mutagenesis experiments, in an attempt to assay the functional significance of genes under positive selection pressure. Another area of interest in my lab involves applying an evolutionary biology perspective to the development and spread of antibiotic resistance. This work involves a range of pathogen species and antibiotics and takes advantage of our extensive isolate collections.
