Assistant Professor of Entomology & Plant Pathology, University of Tennessee
Hi! I’m an Assistant Professor in the Department of Entomology & Plant Pathology at the University of Tennessee Institute of Agriculture.
I study insect viruses – specifically those viruses that have evolved to be beneficial to their hosts, which has repeatedly occurred within insects called parasitoid wasps. Viruses are primarily considered to be pathogenic entities that exploit host organisms for their own gain. However, increasing evidence suggests that viruses often evolve to persist within hosts, and some are even beneficial for their hosts. The best-studied examples of ‘good’ viruses are found within parasitoid wasps, in which viruses are inherited by wasp offspring and act as biological weapons that incapacitate insect hosts of the wasps during parasitism.
A growing number of heritable viruses have been identified in various parasitoid wasp lineages, including wasps that serve as important biological control agents used to suppress agricultural pest populations. Very little is known about most of these viruses, even though some are pivotal for parasitoid wasp success. These viruses could therefore represent hidden aspects of natural biological systems that are used to mitigate pest species.
My lab group uses a combination of molecular biology, manipulative genetics, and genomic sequencing techniques to explore these novel insect-virus interactions and aims to use this knowledge in the future to develop innovative biological control strategies that promote sustainable agriculture.
