Postdoctoral Research Scientist: Receptor-Mediated Enhancement of AAV Gene Delivery

At Lilly, the work is demanding because patients are waiting. We unite caring with discovery to help make life better for people around the world, knowing that every decision, every detail, and every day matters. Headquartered in Indianapolis, Indiana, our over 50,000 employees around the globe take on complex challenges to discover and deliver life‑changing medicines, strengthen how health is understood and managed, and support the communities we serve.

This is hard, urgent, selfless work—but it’s work worth doing. If you’re driven by purpose and ready to bring your best to work that truly matters for patients, we invite you to join us.

Eli Lilly and Company is seeking a motivated Postdoctoral Research Scientist to join our Biotechnology Discovery Research organization in San Diego. This two-year fellowship will investigate receptor‑mediated mechanisms for enhancing adeno‑associated virus (AAV) gene delivery through rational capsid engineering. This role offers exceptional training in viral vector engineering, opportunities for high‑impact publications, and broad exposure to industry‑based translational research.

This project tests the hypothesis that engineering AAV vectors to target specific cell‑surface receptors can dramatically enhance gene delivery, enabling dose reduction, and improved safety. The planned research builds on published evidence that certain AAV serotypes achieve enhanced transduction through receptor engagement. This work will systematically explore whether receptor‑mediated enhancement can be engineered into alternative AAV capsids using displayed targeting ligands, combining capsid engineering, functional screening, and mechanistic analysis.

It is expected that the postdoc will work with an established AAV production platform and collaborate with multidisciplinary gene therapy and analytical teams to carry out the planned research.

• Design, clone, produce, and purify engineered AAV vectors with targeting modifications
• Perform vector quality control including titering (digital PCR), purity assessment, and particle integrity analysis
• Execute cell‑based binding, internalization, and transduction assays using flow cytometry and confocal microscopy
• Perform mechanistic trafficking studies including endosomal escape, capsid uncoating, nuclear entry, and genome processing
• Integrate experimental data to establish structure‑activity relationships and characterize enhancement mechanisms
• Maintain rigorous experimental documentation in electronic lab notebooks
• Present research at scientific meetings and prepare manuscripts for publication (anticipated 1‑2 first‑author publications)

• PhD in Molecular Biology, Cell Biology, Biochemistry, Virology, or related life sciences discipline
• Proficiency in mammalian cell culture including maintenance of adherent and suspension cell lines and standard molecular biology techniques for DNA manipulation
• Experience with quantitative nucleic acid analysis (qPCR or digital PCR)
• Qualified applicants must be authorized to work in the United States on a full‑time basis. Lilly will not provide support for or sponsor work authorization or visas for this role, including but not limited to F‑1 CPT, F‑1 OPT, F‑1 STEM OPT, J‑1, H‑1B, TN, O‑1, E‑3, H‑1B1, or L‑1

• Hands‑on experience with viral vector systems (AAV, lentivirus, adenovirus, or related) including production, purification, AAV capsid engineering, and functional characterization
• Experience with confocal microscopy for live‑cell or fixed‑cell imaging
• Background in protein engineering, nanobody technology, or targeting ligand development
• Experience with intracellular trafficking studies, endocytosis, or nuclear transport
• Familiarity with primary human cell culture
• Experience with flow cytometry for cell‑based assays
• Strong analytical and data interpretation skills
• Ability to work independently and manage multi‑stage research projects
• Excellent written and verbal communication skills with demonstrated ability to prepare scientific manuscripts
