Managing Director, Model Risk Management and Co-Source Services, Financial Services

Vivian Lagan

I am a risk professional with over 20 years’ experience in the financial services industry, encompassing banking, insurance, and professional services. Throughout my career, I have excelled in developing and leading cross-functional teams and projects, as well as establishing strong relationships with clients at senior and executive levels to evaluate and mitigate market, credit, and regulatory risks.

At Grant Thornton UK, I have overseen various advisory and internal audit-related projects within globally diverse organisations and Tier 1 investment banks. Currently, I lead our model risk management (MRM) services, offering guidance on best practice MRM, market and credit risk modelling, and validation techniques for globally diverse organisations and medium-sized firms.

Additionally, I have played a pivotal role in the internal model methodology (IMM) permission and annual attestation process. Noteworthy projects include implementing model risk management frameworks, aligning with SS1/23 requirements, validating credit risk models, and conducting regulatory compliance assessments of risk models.

Before joining Grant Thornton, I held roles in market and credit risk model development, led a model validation team focusing on validating PD, LGD, and EAD models, and headed an internal audit team providing assurance over models in positions held within UK and Irish banks.
