Education

  1. B.S., Agricultural Sciences, Universita' di Firenze, Italy
  2. Ph.D., Plant Pathology, University of California-Davis

Cristina Rosa joined the faculty of the Plant Pathology Department at the Pennsylvania State University in January 2014. She obtained a B.S. at the Universita’ di Firenze, Italy, a Ph. D. in Plant Pathology at the University of California, Davis, and worked as a postdoctoral scholar in Plant Pathology at UC Davis and the Entomology Department at the Pennsylvania State University. She worked on different biological systems, such as the use of RNA interference to control the glassy winged sharpshooter, vector of Pierce’s disease of grapevines, the investigation of the entry of nucleopolyhedroviruses into their caterpillar host epithelial gut cells, the characterization of grapevine viruses and of Elm Yellows disease, and the interactions between insect gut endosymbionts and plant defenses. The purpose of her research is to study the complex interaction between plant viruses and other microbes, plants, and insect vectors in agricultural and natural ecosystems.
