• Technical & Manufacturing Delivery: Drive process control and validation strategies to deliver robust drug substance processes to both internal and external GMP manufacturing sites, ensuring full alignment with regulatory expectations and lifecycle plans.
• Platform and Scale Translation: Direct development and scale-up across varied platforms and equipment, including AMBR and other high-throughput microbioreactors, laboratory-scale stainless-steel and single use systems, pilot-scale equipment, and commercial-scale manufacturing assets. Ensure scale-down models are representative and scientifically justified.
• Strategic Leadership: Align and prioritize departmental technical, scientific, and business goals with broader enterprise priorities to dynamically support an evolving pipeline.
• Financial & Resource Management: Own accountability for team resource allocation, capital, and consumable budgets, ensuring headcount projections and financial targets are met precisely.
• Subject Matter Expertise: Provide expert technical guidance across all aspects of vaccine upstream process development and commercialization for large molecule products.
• Talent Development: Cultivate a high-performance culture by identifying, coaching, and developing talent; actively leveraging both internal and external networks.
• Performance Management: Evaluate team performance accurately through structured, formal appraisal processes and dedicated development support.
• Succession Planning: Establish robust succession plans and actively champion career advancement opportunities for high-potential talent.
