Broadly, I study arthropods (primarily ectoparasites) and their microbial inhabitants. My current research interests are:

  1. Investigation of tick community composition over time using passive surveillance data and museum specimens.
  2. Investigation of tick and other arthropod microbial communities, particularly the transmission of and interactions between endosymbiotic bacteria
  3. Behavior/natural history of ticks off-host
