Biography

Torrence Gill has an enormous passion for insects. This started early in his life growing up and spending much of his time in the woods of North Carolina. As an undergraduate, he took internships at University of California-Davis and Michigan State which helped him rediscovered his passion for insects, with a new found love of molecular biology. During his doctoral research, his research focused on understanding how polydnaviruses (which exist in genomes of parasitoid wasps) are able to suppress the immune response of the host (caterpillars). He realized at this time that he wanted to conduct research that can become directly applied to help farmers minimize crop losses to insects. This experience with insect and plants, lead to a smooth transition to understanding how pathogens and plants interact and again applying the research to control pathogen spread and crop losses. At the end of the day, he would consider himself a crop protection specialist who tries to control the insect and pathogen damage on economically important crops.

Research

  • Assess insecticidal activity of cys-motif genes associated with Campoletis sonorensis Ichnovirus (CsIV)
  • Determine the role of each cys-motif protein during parasitism of Fall armyworm by Campoletis sonorensis
  • Test efficacy of Thymol derived nanoemulsion particles on disease transmission in many economically important crops
