Postdoctoral Research Associate
My current research work focuses on two major goals: 1. Identification of gut receptors in aphids that are involved in uptake of luteoviruses, and 2. Examination of mechanisms of transcytosis across the insect gut. Both of these areas of research have the potential to provide novel... more

Ph. D. Candidate

Graduate Assistant-Research
Insect viruses have developed ways to surpass the natural barrier of the gut epithelium to establish an infection in their host. This ability of viruses could be beneficially employed for insect pest management purposes, and used as a delivery system to transport important toxins to the hemocoel.... more
