During my 25+ year scientific career, I have studied pathogen-host interactions in various infectious disease models including Avian and Swine Influenza viruses (AIV, SIV), African Swine Fever virus (ASFV), Rift Valley Fever virus (RVFV), Vesicular Stomatitis virus (VSV), Schmallenberg virus (SBV), animal prion diseases and Borna Disease Virus (BDV). On these topics, I have published more than 250 peer-reviewed scientific manuscripts. I am an editor for Virus Genes and serve on editorial boards for other scientific journals. Currently, I am the Director of the Center of Excellence for Emerging and Zoonotic Animal Diseases (CEEZAD) and the NIH COBRE Center on Emerging and Zoonotic Infectious Diseases (CEZID). I hold the prestigious Regents Distinguished and University Distinguished Professor appointments at Kansas State University.
The overall goal of my research is to investigate zoonotic, emerging and transboundary diseases of livestock focusing mainly on viral diseases. My lab established the first reverse genetics system for SIVs, made seminal contributions to the development of a modified live SIV vaccine (sold in the U.S. as Ingelvac Provenza™), and contributed to understanding the virulence of the reconstructed 1918 "Spanish Flu" virus in livestock. We also worked on the isolation and characterization of novel swine influenza virus subtypes including the H2N3 reassortant virus and the 2009 pandemic H1N1 virus, and studied their zoonotic potential using nonhuman primate models. We identified an atypical BSE case with a causative mutation ("genetic BSE"), used gene-editing approaches to develop the first prion protein knock-out cattle that are resistant to prion infection, and provided valuable information on host range of animal prions essential for risk analysis.
Our RVFV work led to the development of novel domestic and wild ruminant models for RVF and a safe, efficacious, and DIVA-compatible subunit RVF vaccine. For ASFV, we are developing subunit and modified live virus vaccine candidates as well as point-of-need diagnostic tools (PenCheckTM) to protect swine from this devastating disease. Our recent work focuses on the establishment of preclinical animal models for SARS-CoV-2 in pigs, cats, hamsters and ferrets in order to evaluate the efficacy of COVID-19 vaccines and therapeutics. As founding Director of the DHS CEEZAD and the NIH CEZID Centers, our laboratory is supporting NIH, DHS and USDA in protecting U.S. public health and agricultural systems from devastating animal and zoonotic diseases
