Further Details:
I am an Associate Professor in Mathematical Finance and Tutorial Fellow in Mathematics at St Catherine's College. I am Co-Editor-in-Chief of Applied Mathematical Finance, and serve on the editorial board of The Journal of Computational Finance and the International Journal of Computer Mathematics. I have a doctorate from the University of Heidelberg in scientific computing and a degree from Linz in applied mathematics.
Teaching:
I teach various Masters level courses in the areas of computational finance, numerical analysis and partial differential equations. I have examined on several Masters programmes and numerous PhD committees at and outside Oxford, and was Course Director of the professional MSc in Mathematical Finance at Oxford for over six years. I am a tutor for Applied Mathematics at St Catherine's College, Oxford, and have occasionally served as Director of Studies.
