Main research interests
My research interests include pathogenesis of human and animal viral diseases and the development of screening assay platforms for antiviral drugs and animal models of virus infections with the aim of developing antiviral drugs. In particular, human and animal coronaviruses, such as feline infectious peritonitis and MERS, human norovirus and influenza virus are the focus of my research.
Teaching
I teach feline viral diseases in the Veterinary Virology course (DMP 822) for second year veterinary students. I also teach antivirals and resistance in Pathogenic mechanism of viruses course (DMP 910) for graduate students.

Selected Publications
1. Antiviral drug development for feline infectious peritonitis (FIP). FIP is a fatal systemic coronavirus infection and a leading cause of death in young cats for which no effective preventive or treatment is available. Over the years, we have developed antiviral compounds for FIP and demonstrated their effectiveness in cats with experimentally-infected or naturally-occurring FIP.

2. Antiviral drug development for human norovirus, coronavirus and influenza virus. Coronavirus, picornavirus and caliciviruses have highly conserved viral proteases that may serve as targets for developing broad-spectrum antiviral drugs. We have been focusing on developing protease inhibitors for these viral diseases and elucidating resistance mechanisms associated with antiviral drugs.

3. Virus entry and cellular factors important for virus replication. Understanding viral entry and replication steps offers important insights into viral pathogenesis and may provide potential targets for antiviral drug development. We have been investigating cellular pathways or factors that are important for the replication of viruses in in vitro and/or in vivo systems.
