Areas of Interest

  • Pathogenesis of retroviral infection
  • Mechanisms of inflammation in recurrent airway obstruction
  • Development of novel diagnostic assays

The main focus of the laboratory is to study the interaction of retroviruses with their host. Using the feline immunodeficiency virus as a model system we seek to explore how the host responds to infection at the cellular and molecular level.

Other research explores host-environment interactions in the development and progression of lung inflammation of the horse, with particular emphasis on cellular and molecular responses of the respiratory epithelium and role of lung leukocytes.
