Research Focus

My laboratory focuses on understanding the pathogenic mechanisms of the spirochetal bacteria Borrelia burgdorferi, the causative agent of Lyme Disease. B. burgdorferi is a unique and interesting bacteria that largely relies on dynamic genetic regulation and antigenic variability to establish infection and elicit adaptation within the host. The overall goal of our research is to understand the molecular mechanisms used by B. burgdorferi to regulate pathogenesis. We are primarily interested in characterizing B. burgdorferi environmental sensing and genetic and physiological adaptation to the host and tick. Ongoing interests in the lab include: characterizing hypothetical proteins which are unique to B. burgdorferi, investigating the role of signal transduction cascades at the host-Borrelia interface, and investigating the production and regulation of B. burgdorferi cyclic nucleotides.
