Applied inter and intra-veterinary diagnostic database handling and connectivity concepts to collate, analyze, model, and interpret diagnostic data for epidemiological usage and applications.
Initiatives to support and implement animal health preparedness programs, such as the US Swine Health Improvement Plan.
Usage of next-generation sequencing assembled outputs for farm or production-system-specific PRRSV epidemiological investigations
