Teaching and Service

I serve as Course Coordinator and Instructor in the DMP822 Veterinary Virology course (3 credit hours) for veterinary students in the second year of the professional curriculum.  My lectures include viral diseases of swine, equine, avian and canine species.  My service role includes diagnostic test development for viral diseases and microbiome characterization. 


My research primarily focuses on understanding how the microbiome plays a role in outcome following viral infection in swine as well as the role of feed in the introduction and transmission of swine viruses.  Research projects have included porcine reproductive and respiratory syndrome virus (PRRSV), porcine circovirus type 2 (PCV2), porcine epidemic diarrhea virus (PEDV), African swine fever virus (ASFV), classical swine fever virus (CSFV), and pseudorabies virus (PRV).
