Teaching Activities

I teach physiology, genetics and biotechnology to veterinary students. I also work on a project to create a comprehensive Web-based hypertext for use in teaching pathophysiology.

Research Interests -- Infectious Disease

My current interests focus on viral diseases that affect domestic and wild animals and spillover into human populations. Current projects include:

  • Working to understand the pathogenesis of West Nile virus infection in domestic animals, birds and reptiles, and to develop and test vaccines to protect against that disease.
  • Determining vertebrate and mosquito host competency for Japanese encephalitis, and elucidating the pathogenesis of infection in those creatures.
  • Evaluating the potential role of bats in transmission of a number of viruses.
  • Understanding the human-animal interface as it relates to transmission of avian influenza viruses.
  • I serve as Director of the Animal Models Core of the Rocky Mountain Regional Center of Excellence for Biodefense and Emerging Infectious Disease, and in the capacity supervise numerous trials to evaluate vaccines and therapeutics to protect against a broad range of pathogens.
