Dr Samuel Cohen
Research Interests: 

I am a University Research Lecturer in the Mathematical and Computational Finance Group. My main research interests are in the areas of stochastic analysis and mathematical finance. In particular, I work with Backward Stochastic Differential Equations (BSDEs), which arise in various areas in stochastic control and mathematical finance. I am interested in problems associated with decision making in the presence of risk and uncertainty.

A key problem in risk-averse decision making is time-consistency - "How can I be sure that tomorrow's decisions will satisfy today's objectives?" To guarantee time-consistency, we must ensure that the objective pursued satisfies certain properties. These properties, in general, are satisfied by solutions to BSDEs.

Professor Mike Giles
Research Interests: 

I am Professor of Scientific Computing, a member of the Oxford-Man Institute of Quantitative Finance, and Associate Director of the Oxford e-Research Centre. I used to work at MIT and in the Oxford University Computing Laboratory on computational fluid dynamics applied to the analysis and design of gas turbines, but more recently I have moved into computational finance. 

My focus is on improving the accuracy, efficiency and analysis of Monte Carlo and finite difference methods. Recent research highlights include the use of adjoint techniques to compute sensitivities, and a new multilevel Monte Carlo method.

I am also interested in various aspects of scientific computing, including high performance parallel computing, and in the last couple of years I have been working on the exploitation of graphics cards for scientific applications in both finance and computational engineering.

I am a University Lecturer in the Mathematical Institute. I obtained my PhD from the University of Cambridge and held post-doctoral positions at the University of Cambridge and the University of California, San Diego. I previously held academic positions at the Universities of Edinburgh and Bristol before moving to Oxford in 2000.

Dr Raphael Hauser
Research Interests: 

I am a member of the Numerical Analysis and Computational Finance Groups at the Mathematical Institute of the University of Oxford, and a Tutorial Fellow in Applied Mathematics at Pembroke College Oxford. Before joining Oxford as a University Lecturer, I was a postdoc at the University of Cambridge. I received my PhD in Operations Research from Cornell University in 2000. My first degree was in maths; after studying at EPFL Lausanne for the first two years, I transferred to ETH Zurich where I received a Dipl.Math ETH. 

My research interests focus on convex optimization and convex analysis. On the theory side I'm interested in complexity theory and the probabilistic analysis of algorithms, as well as in condition numbers and the design of algorithms. I also work on the theory of optimal alignments of random sequences. A large deviations approach allows to reduce many of the salient questions to convex analysis. On the applications side, I'm interested in the use of optimization models in mathematical finance, in particular in robust portfolio optimization and risk management.

Research Interests: 

I am a University Lecturer at the Mathematical Institute and a member of the Oxford-Man Institute of Quantitative Finance.  I obtained a Ph.D degree in Financial Engineering from the Chinese University of Hong Kong, and was then a postdoctoral fellow in the same university. I was an assistant professor in the National University of Singapore in September 2006--Jan 2009.

Professor Terry Lyons FLSW FRSE FRS
Research Interests: 

I am the Director (and a founding member) of the Oxford Man Institute of Quantitative Finance, and the Wallis Professor of Mathematics; previously I was the Director of the Wales Institute of Mathematical and Computational Sciences (WIMCS; 2008-2011). I came to Oxford in 2000 having previously been Professor of Mathematics at Imperial College London (1993-2000), and before that I held the Colin Maclaurin Chair at Edinburgh (1985-93).

My long-term research interests are all focused on Rough Paths, Stochastic Analysis, and applications - particularly to Finance and more generally to the summarsing of large complex data. That is to say I am interested in developing mathematical tools that can be used to effectively model and describe high dimensional systems that exhibit randomness. This involves me in a wide range of problems from pure mathematical ones to questions of efficient numerical calculation.

Further Details: 

Stochastic analysis. This is the area of mathematics relating to the rigorous description of high-dimensional systems that have randomness. It is an area of wide-reaching importance. Virtually all areas of applied mathematics today involve considerations of randomness, and a mobile phone would not work without taking advantage of it. Those who provide fixed-rate mortgages have to take full account of it. My interests are in identifying the fundamental language and the basic results that are required to model the interaction between highly oscillatory systems where the usual calculus is inappropriate. If you google ‘Rough Paths’ and ‘Lyons’ you will find further information. My St Flour Lecture notes provide a straightforward technical introduction with all the details put as simply as possible. A more general introduction can be found in my talk/paper to the European Mathematical Society in Stockholm in 2002.
My approach is that of a pure mathematician, but my research has consequences for numerical methods, finance, sound compression and filtering. At the moment I am (speculatively) exploring their usefulness in understanding sudden shocks on dynamical systems, and also trying to understand the implications for geometric measure theory. The focus of my research directed to ‘Rough paths’ can be viewed as a successful approach to understanding certain types of non-rectifiable currents.
I actively look for applications in the mathematics I do, but my experience has led me to believe strongly in the importance of being rigorous in the development of the core mathematical ideas. For me, the word proof is synonymous with the more palatable ‘precise, convincing and detailed explanation’, and I believe it is important, even essential, to find rigorous proofs of the key mathematical intuitions so that mathematics can reliably grow and ideas can be passed on to the next generation.

I also tutor Applied Mathematics to undergraduates at my college, Lady Margaret Hall.

Dr Jan Obloj
Research Interests: 

I am a University Lecturer at the Mathematical Institute, Fellow of St John's College and a member of the Oxford-Man Institute of Quantitative Finance. Before coming to Oxford I was a Marie Curie Post-Doctoral Fellow at Imperial College London. I hold a Ph.D. degree in Mathematics from University Paris VI and Warsaw University.

I've been focusing recently on the robust approach to Mathematical Finance, which does not start with an a priori model but rather with the information available in the markets. My general interest are in Mathematical Finance and its interplay with Probability Theory and I look at a number of different problems where tools from martingale theory and stochastic analysis can be applied. Examples include: market completion using options, volatility derivatives and extrapolation of implied volatility surface, portfolio optimisation under pathwise constraints and hedge-funds managers incentive schemes.
