This postdoctoral position will focus on developing optimized flow virometry techniques and workflows for therapeutic tLVVs with the goal of developing reproducible single‑particle measurements and understanding whether these measurements predict tropism, functional potency, and safety in preclinical models.

In this position, the Postdoctoral Scholar, Advanced Flow Virometry, will develop and apply flow virology methods to characterize targeted lentiviral vector quality attributes for in vivo applications. The role focuses on generating reproducible single‑particle measurements, comparing flow virology with established analytical methods, linking particle phenotypes to transduction, potency, and safety outcomes, and building cross‑functional scientific insight that supports analytical and process development in cell and gene therapy.

The scholar will interpret complex data sets, collaborate extensively with complementary internal teams, and communicate findings in scientific and cross‑functional forums.

• Design, optimize, and execute advanced flow virology workflows to characterize targeted lentiviral vector particle heterogeneity, envelope integrity, aggregation, and contaminant extracellular vesicles at the single‑particle level.
• Perform comparative analytical studies against established methods such as Western blot, DLS, SEC‑MALS, ELISA, and density gradient approaches, and generate validation data sets that assess agreement, specificity, and reproducibility of flow virology measurements.
• Correlate particle phenotypes with functional outcomes, develop statistical models linking analytical measurements to transduction and potency, and communicate results through group meetings, cross‑functional forums, internal scientific showcases, and external scientific conferences as appropriate.
• Development, training, conferences, internal meetings, and symposia.

• PhD in Virology, gene therapy, flow cytometry/flow virology, analytical development relevant to role, bioengineering, biotechnology, or related discipline with 0-1 years of experience is required.
• Expertise in virology, analytical characterization, bioengineering, cell biology, biotechnology, or a related scientific discipline relevant to viral vectors and single‑particle analysis.
• Position will require generation, use, and testing of lentivirus particles. Applicants should be comfortable working in BSL2+ laboratory conditions.
• Demonstrated ability to design experiments, analyze complex data, and compare emerging analytical methods with established assays using scientifically rigorous approaches.
• Ability to work effectively across cross‑functional teams and communicate scientific concepts and results clearly to technical and non‑technical audiences.
• Experience with statistical interpretation, correlation analyses, and data‑driven…
