Molecular pathogenesis; Lyme disease and human granulocytic ehrlichiosis

I studied Borrelia burgdorferi, the etiologic agent of Lyme disease and the agent of human granulocytic ehrlichiosis. Most recent projects in the lab included the study of the ecology of Lyme disease, human granulocytic ehrlichiosis, in Minnesota.
