• Perform data acquisition, analysis, and documentation using standard flow cytometry software (FlowJo, Sony Cell Sorter software, FCS Express, etc.).
• Establish and maintain best practices for instrument operation, maintenance, performance and data reproducibility for a Sony MA900 (and/or other cell sorters, including spectral, e.g., BD, Cytek, etc.)
• Support flow-based validation studies under CLIA/CAP guidelines, ensuring traceability and documentation compliance.
• Process whole blood, bone marrow, PBMC, and BMMC samples for cell isolation, enrichment, and sorting.
• Support workflows downstream of sorted material including nucleic acid extraction, NGS library prep/sequencing, etc.
• Participate in cross-functional troubleshooting and optimization across clinical, R&D, and computational biology teams.
• Collaborate closely with clinical and R&D teams to ensure seamless tech transfer and testing execution.
• Assist in the development and refinement of laboratory procedures and workflows while maintaining complete and accurate records.
