My dissertation research focused on Lyme disease ecology, a vector-born zoonotic disease that is endemic to the United States, Europe and Asia. For the past 4 years I have investigated the relationship between the prevalence of Lyme disease and the impacts of a devastating forest pathogen, Sudden oak death (SOD). SOD is killing scores of oak trees in California’s coastal oak woodlands and changing the habitat, resource base, and abiotic conditions for vertebrate reservoirs of the disease-causing bacterium, Borrelia burgdorferi. Tick hosts such as mice (Peromyscus spp.) and woodrats (Neotoma fuscipes), as well as disease vector, the western black-legged tick, Ixodes pacificus are all potentially impacted by SOD.
