• Act as a key site/scientific representative during sponsor reviews, CRO oversight, audits, and regulatory inspections (e.g., MHRA, FDA).
• Ensure clinical data quality, accurate source documentation standards per ALCOA++ principle and endpoint reliability.
• Support staff induction, onboarding, and ongoing training in clinical assessments, study procedures, and GCP compliance.
