Christoph Reisinger

Associate Professor in Mathematical Finance, University of Oxford

University Lecturer in Mathematical Finance at the Mathematical Institute, and Tutorial Fellow in Mathematics at St Catherine's College, University of Oxford.

Current research includes, mathematically, the numerical analysis of high-dimensional PDEs, non-linear PDEs and variational inequalities, simulation of SPDEs, Bayesian techniques and parameter estimation problems. Application areas include the pricing of equity and credit basket derivatives, calibration of financial instruments, early-exercise options and valuation and investment in incomplete markets.
