Professional Awards:
Norden Distinguished Teacher Award, 1999
Pfizer Research Award for Research Excellence, 2002
Inducted into Veterinary Honor Roll, Morris Animal Foundation, 2003
Professional and Research Interests:
- Immunologic responses to infectious disease
- Hematopoiesis
- Diagnostic cytology and hematology
- Metabolic disease
- Interactive and computer-assisted teaching methods
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.
