Profile Summary

Ph.D. scientist with 20+ years of experience in infectious diseases, molecular biology, immunology, and vaccine development. I have led interdisciplinary programs involving DNA and viral vector platforms, immunotherapies, stable cell line development, and regulatory-compliant IND-enabling studies. My background includes extensive GLP/GCP-regulated preclinical research, assay development, bioanalytics, and translational program support. I bring strong expertise in project management, technology transfer, and strategic planning across biotech and pharmaceutical environments. I have recently founded Vaxonyx, a biotechnology startup at the HudsonAlpha Institute of Biotechnology focused on developing next-generation DNA device–free delivery platforms for vaccines, gene therapy, and immunotherapy, stable cell line, recombinant and native native antigen production. I am passionate about providing high-quality scientific consulting and helping organizations accelerate innovation in diagnostics, therapeutics, and vaccine development.
