Research in my laboratory is focused on the pathogenesis of bacterial obligate intracellular parasites (BOIPs). BOIPs encompass several genera (e.g., Anaplasma, Rickettsia, Coxiella and Chlamydia) of clinically significant pathogens, some of which are zoonotic (i.e., transmit from animals and humans). Unlike most bacteria, BOIPs require invasion of a eukaryotic host cell to reproduce and cause disease. Because BOIPs have evolved to parasitize their host cells, their genomes have undergone extensive streamlining (reduction) at the expense of metabolic capacity. Largely focused on Coxiella burnetii and Chlamydia trachomatis, we seek to understand how pathogen metabolic capacity and plasticity shape the host-pathogen interaction.
