Research

My research interests include viral disease concerns for the U.S. swine industry, e.g., porcine reproductive and respiratory syndrome virus (PRRSV), Senecavirus A (SVA), swine enteric coronaviruses (SECV), as well as potential emerging livestock diseases. Specifically, I evaluate the host response to swine viruses and collaborate as part of a team to identify mechanisms to modulate innate and adaptive immune responses to swine viral pathogens using methodology that combines in vitro and in vivo studies using both cutting-edge and classical techniques to: 1) identify genes involved in the host response to infection, including coding and non-coding RNA library construction, high-throughput genomic sequencing, porcine whole genome sequence analyses, and real-time (reverse-transcriptase polymerase chain reaction [RT-PCR]); 2) application of novel immunological assay systems to determine the components of the porcine immune system involved in response to pathogen insult identifying patterns, changes, or genes of interest in metagenomic or genomic data.

My short-term goals are to develop new, or modify established, techniques to characterize the host response to swine viruses at the molecular and cellular levels; to analyze the massive datasets generated by high-throughput genomic experiments and to apply this knowledge towards high-impact products such as the design of novel vaccines and other disease intervention strategies. This research is complex in nature and involves integration of concepts and approaches from molecular biology, immunology and genetic theory to delivering cutting-edge, scientific tools and innovative solutions for American farmers, producers, industry, and communities.

My long-term goal is to advance the understanding of the genetic component of disease expression in livestock. The goal is to utilize cutting-edge technologies to investigate livestock diseases and how the pathogen alters the host’s immune response. This will enable efficient production of animal protein for a growing global population. Animal health is one of the most volatile costs in the efficient production of livestock and research to improve animal health helps to ultimately feed the world.
