• Ensure bioassays are mechanistically relevant, connecting product biology to assay design, performance, and control strategies
• Provide strategic leadership for CMC bioassay development, supporting IND/BLA submissions and commercial readiness
• Interpret and apply global regulatory guidelines (e.g., ICH, FDA, EMA) to assay development and lifecycle activities
• Support regulatory filings, health authority questions, and interactions related to bioassays
• Partner cross-functionally with Quality, QC, and Analytical Sciences & Technology (AS&T) to enable method transfer, validation, and commercialization
• Drive resolution of bioassay-related challenges, including investigations, deviations, and comparability assessments
• Lead through influence across cross-functional teams, setting priorities aligned with program and organizational goals
