Cross-Functional Leadership & Strategic Consultation

• Act as a key statistical thought partner to Clinical Operations, Regulatory Affairs, R&D, and Quality teams.
• Aid in translation of complex statistical results into clear, actionable insights for diverse technical and non-technical audiences.
