 Bahman Angoshtari
Research Interests: 

I am a fourth year D.Phil. student in Mathematical and Computational Finance Group, and a student member of Oxford-Man Institute of Quantitative Finance. My research, supervised by Prof. T. Zariphopoulou, lies on the interaction between Portfolio Choice Theory and Financial Econometrics. Currently, my focus is on dynamic asset allocation models in cointegrated markets, with applications including pairs/spread trading and statistical arbitrage techniques.

 Alice Dub
Research Interests: 

I am a second year DPhil student working in the Mathematical and Computational Finance Group and an associate member of the MAN Institute of Quantitative finance. I hold a Diplom in Mathematics and Business Studies from Ludwig- Maximulians University in Munich as well as an MSc in Mathematics fromUniversity of St Andrews. My Supervisor is Dr Ben Hambly and I am a member of St Anne's College.

Currently I am looking at the Merton Problem of optimal investement with intermediate consumptions. Here I am cosidering perturbations to the well known model. In addition l want to look at similar setups but with non-linear weath dynamics trying to find optimal portfolio and consumption quantities for general as well as particularly chosen utility functions.

 Peter Spoida
Research Interests: 

I am a second year DPhil student in Mathematical and Computational Finance group.

My research interests lie in probability theory and its interplay with Mathematical Finance. Together with Jan Obłoj I try to develop the robust pricing and hedging framework further to allow for more flexible incorporation of both, market and statistical information. In particular, we try to incorporate statistical confidence intervals on total realised volatility and understand the consequences for pricing, pathwise hedging and forms of arbitrage. Key mathematical tool for doing this include optimality properties of solutions to the Skorokhod embedding problem and pathwise stochastic calculus.
