Development and evaluation of innovative RNAi-based products targeting multiple citrus pathogens and pests
Our team at UC Riverside has discovered a novel species of virus-like RNA in citrus. My current work is focused on exploring the tremendous potential of this RNA as a VIGS vector by (i) the delivery of wild type and recombinant infectious clones in citrus, (ii) evaluating its effects on commercial citrus in field conditions and (iii) studying its natural transmission via insect vectors and pollen.
Postdoctoral Research Associate
Development of novel insect-delivered virus tools for crop improvement and protection using genetic engineering
At NC State University, my research contributed to developing new genetic engineering tools to efficiently and rapidly achieve a plant trait modification in a desired manner. Our team attempted to use a natural two-step delivery system (plant viruses and insect vectors) to transfer modified genes to plants with an overarching goal of conferring protective traits to target plants within a single growing season.
Postdoctoral Research Associate
Plant- vector-virus interactions: molecules, ecology and applications
This project at UGA explored how economically important plant viruses interact with their host plants and insect vectors. More specifically, I studied the virus-mediated changes in host plant biochemistry, and behavior and fitness of insect vectors. I studied three diverse pathosystems, each involving different viruses, vectors and plants.
Ph.D. (Microbial Ecology)
Interactions between plant growth promoting rhizobacteria, foliar-feeding insects and higher trophic levels
This multidisciplinary research project explored the interactions between soil microbes, plant-insect herbivores and higher trophic levels. I used molecular, statistical and biochemical approaches to study these interactions. Through a series of manuscripts, we showed that addition of common bacterial species as a simple seed inoculant can alter plant microbiome, plant and insect fitness, and natural enemy responses.
Master of Science (Entomology)
Characterization of gut microflora of silkworm, Bombyx mori L.
My masters research involved studying gut microbes of the silkworm, Bombyx mori using microbial, biochemical and molecular approaches. I further studied the role of select gut microbes in host insect infection and probiotics.
Master of Professional Studies (Plant Breeding and Genetics)
Breeding Sweet Sorghum as a dual purpose bio-fuel and food crop for India
This project presented a summary of the findings and recommendations for improving sorghum as a dual purpose ethanol and grain crop in India. This work reviewed the key features that make sorghum particularly amenable to genetic improvement and uniquely suited for Indian agriculture.
