Responsible for research and development of new products used for molecular biology, next generation sequencing, RNA and DNA FISH, and synthetic biology based on our in-house DNA and RNA synthesis platform.

Global Vaccines, Inc. Research Triangle Park, NC

• Production of a VEE virus derived adjuvant, GVI3000, using ATCC certified Vero cells, RNA transcription, electroporation, and ultracentrifugation.
• Design and cloning of a new RNA expression system to increase the safety of GVI3000 production.
• Design, cloning and testing for virulence and safety of recombinant GVI3000 particles containing a near complete genome of an attenuated VEE virus that could theoretically occur during GVI3000 production to ensure that.
• Demonstrated that the cytopathic effect safety test used to detect propagation-competent recombinant virus can detect down to 1 PFU of virus (GVI3000 is not propagation-competent).
• Quantification of GVI3000 infectious particles using immunofluorescence and flow cytometry.
• Conducted a year-long longevity study of the immunological response in mice to GVI3000 combined with H5N1 influenza vaccine, analyzing serum and mucosal antibody titers by ELISA and T cell responses by ELISpot.

• Use of mice knocked out for different innate immune recognition and signaling proteins to determine which innate immune pathway is important for the GVI3000 adjuvant effect using a model antigen.
• Investigated the innate immune response to GVI3000 in mouse serum and lymph nodes at several timepoints by analysis of type I interferons, as well as several cytokines and chemokines either by bioassay, ELISA, or.
• Harvested and cultured bone-marrow derived dendritic cells from knockout mice that were then infected with GVI3000 and vesicular stomatitis virus.
• Optimized the electroporation of human A549 cells with siRNA and siRNA-expressing DNA plasmids to knockdown particular innate immune proteins.
• Wrote an SOP for the detection of GVI3000 RNA genomes by quantitative real-time PCR.
• Quantified the number of genomes of GVI3000 particles per lot and then determined the ratio of genomes to actual infectious units of GVI3000.
