Expertise / Research Area

Professor, Associate Professor, Assistant Professor, Visiting Assistant Professor at the Veterinary Medical Research Institute, ISU, 1977 - present.  Work on bovine respiratory diseases and infectious bovine keratoconjuncitivitis. In these areas my interest centers on molecular pathogenesis, host defense mechanisms involving epithelial surfaces, naive and acquired immune responses, role of immune responses in disease production. Applications that result in immunogens or diagnostic tests are pursued as they evolve from the above studies. Infectious agents studied involve bovine respiratory mycoplasmas with emphasis on Mycoplasma bovis and Mycoplasma dispar, bovine ocular mycoplasmas, pathogenic and non-pathogenic Moraxella spp, bovine viral diarrhea virus, and bovine papular stomatitis virus. Other interests are mycoplasmal infections of sheep and goats.


I currently teach VMPM 378 (Case Studies IV) to the sophomore veterinary students in the Spring semester. This is a case-based basic sciences review course. I also assist with the teaching of the corresponding Univ. of Nebraska course VM 514 (Clinical Cases IV). Provide selected lectures for graduate courses.
