• Research new and emerging algorithms to ensure model approaches are fit-for-purpose and aligned to industry best practice.
• Ensure models meet regulatory, governance, and internal risk standards.
• Collaborate with model development teams and business stakeholders, delivering effective challenge and assurance.
