Teaching and Service

I serve as the Course Coordinator and teach a portion of the DMP722 Veterinary Virology course (3 credit hours) to veterinary students in the second year of the professional curriculum. My lectures include viral diseases of swine, equine, avian, and canine species.  My role within the Kansas State Veterinary Diagnostic Laboratory is to provide outreach service and resources to veterinary students and practicing veterinarians.  


My research primarily focuses on viral diseases of swine in the areas of clinical disease response and pathogenesis, effects of the microbiome and co-pathogens, and the risks of virus transmission. Research projects have included porcine reproductive and respiratory syndrome virus (PRRSV), porcine circovirus type 2 (PCV2), porcine epidemic diarrhea virus (PEDV), and African swine fever virus (ASFV). My interests are in translational research and the integration of clinical health data with molecular factors affecting viral pathogenesis.
