• Provide scientific and regulatory guidance to cross‑functional project teams, supporting strategic decisions, regulatory readiness and continued development of regulatory expertise.
• Represent the US region on cross‑functional drug and biotherapeutic development teams and help ensure alignment with US regulatory expectations.
• Prepare, review, or oversee regulatory documents, including pre‑submission conference requests, protocol concurrences, and Effectiveness and Target Animal Safety technical sections, helping the US Innovation RA team maintain consistent, high standards.
• Work directly with FDA CVM/USDA CVB to discuss and agree on development pathways, protocol concurrence, labeling text and product approval.
