Dr. Cristin Buescu is a Senior Lecturer in Financial Mathematics at King's College London, Department of Mathematics. She holds affiliations with the Financial Mathematics research group and has held visiting positions at Imperial College London, LSE, and the University of Sydney. Her research focuses on counterparty credit risk (XVAs), portfolio management with friction factors (taxes/transaction costs), utility maximization, and stochastic control problems. She earned a PhD in Optimal Portfolio Management from the University of Alberta (2004).

• Education: PhD in Optimal Portfolio Management (University of Alberta, 2004)

Her research interests include advanced mathematical finance topics such as nonlinear valuation frameworks, funding costs, and the integration of real-world market frictions like taxes and transaction costs into optimal investment strategies. She has published extensively on XVAs, stochastic control applications, and numerical methods for free-boundary problems. Recent work explores post-retirement investment strategies under longevity risk and the competition between traditional stochastic models and machine learning approaches in portfolio optimization.

Her publications span journals like Scandinavian Actuarial Journal, Mathematics, and Algorithmic Finance, addressing topics such as collectivised pension funds, nonlinear valuation approaches, and cointelated pairs optimization. She is a member of professional societies including the Bachelier Finance Society and the London Mathematical Society.
