Research/Career Interests: 
  • Hematology
  • Diagnostic cytology and hematology
  • Metabolic disease
  • Medical education/curriculum

My research interests are primarily in immune response to infectious disease, hematology and metabolic diseases. We do most of our work with camelids (llamas and alpacas), but also collaborate on studies in a variety of animal species. Our particular interest is in Mycoplasma haemolamae, an organism that affects red blood cells of llamas and alpacas. We developed a PCR assay for the organism and have used it to study multiple aspects of the infection.
