Research Interests

  • Epidemiologic studies related to the prevention and control of Mycobacterium avium subsp. paratuberculosis (Johne’s disease), Salmonella, and other manure-cycle pathogens, and to the prevention and eradication of Mycobacterium bovis (bovine tuberculosis) in cattle and other food-producing animals.
  • Use of analytic epidemiologic methods directed towards control of economically important disease conditions in livestock and poultry, including monitoring and surveillance, herd prevalence estimation and testing, risk factor modeling, risk assessment, and use of data from complex surveys.

Clinical Interests

  • Prevention and control of infectious diseases in cattle, including Johne’s disease and bovine tuberculosis.
