Dr. Centurion's research focuses on Treponema pallidum, the etiologic agent of syphilis.

  1. Pathoadaptive mutations
    In collaboration with Dr. Evgeni Sokurenko, we are studying the genome-wide genetic diversity within T. pallidum species and subspecies. These studies use population genomics by analyzing gene presence/absence and single nucleotide polymorphisms across genomes of different strains. The primary goal of is to identify adaptive mutations that facilitate bacterial survival in specific habitats and, in particular, sequence changes associated with different clinical outcomes in humans and the animal model
  2. Congenital syphilis
    Research interest is directed at understanding patterns of antibody responses in pregnant women and newborns during syphilis infection. Specifically, we are interested in antibody responses to T. pallidum antigens in pregnant women as predictors of effective treatment, and immunoproteome profiles in mothers and newborns associated with particular clinical outcomes
