Research Interests

  • My research program aims to understand the intricate interplays between viruses and their plants hosts during infection and pathogenesis. Areas of research interests include gene expression and replication of RNA and DNA viruses, mechanisms of plant resistance to viral infections and resistance-breaking by RNA viruses, recombination and evolution of RNA viruses, and pathogenomics studies using the state-of-the-art resequencing microarray and high-throughput sequencing technologies
