Research
The overall goal of my research
is to investigate emerging disease problems in swine, with an
emphasis on viral infections. The bulk of these efforts are directed
at elucidating molecular mechanisms of viral persistence and
virulence caused by porcine reproductive and respiratory syndrome
virus (PRRSV) and porcine circovirus 2 (PCV2) considered the most
important infectious disease problems of swine. In addition to their
economic impact, both viruses represent relevant biological systems
for understanding mechanisms of viral pathogenesis, including
evasion strategies. Research focuses at the population, cellular and
molecular levels and incorporates the use of reverse genetic
systems. The results are being applied to the development of novel
vaccine and diagnostic testing strategies.
