Department

Veterinary Preventive Medicine

Professional Training and Experience

  • MS, Purdue University
  • PhD, University of Missouri-Columbia

Research Interests

  • Molecular and cellular mechanisms by which positive stranded RNA viruses alter the metabolism of host cells and how these viruses mediate persistence

Research Summary

  • Molecular and cellular mechanisms by which positive stranded RNA viruses alter the metabolism of host cells and how these viruses mediate persistence. As a model for our studies, our laboratory is focused on the order Nidovirales (coronaviruses and arteriviruses), using the porcine arterivirus, porcine reproductive and respiratory disease virus

Professional Service

  • Editorial Board for Journal of Veterinary Diagnostic Investigation (1998-2006)
  • Co-chairperson of the Diagnostic Virology Subcommittee of the American Association of Veterinary Laboratory Diagnosticians (2000-2005)
