Our research in financial engineering focusses on derivative pricing; and applying machine learning techniques time series prediction and the hedging of foreign exchange risk.
Managing foreign exchange risk
ARC Linkage Grant: LP110200413
Partner/Collaborating Organisation: Westpac Banking Corporation
Financial institutions are required to absorb risks associated with foreign exchange (FX) transactions. This work involves applying recent parallel computing and machine learning techniques to better understand and manage such exposure. An environment is being developed to facilitate the testing of risk management strategies and provide an interface to scalable computational resources. The environment will be used to develop improved techniques for: customer flow and exchange rate prediction, hedging strategies, and FX market models. This research will potentially enable national banks to better quantify and manage risk, allowing them to be more competitive in global FX markets.

Cluster and FPGA-based Acceleration of Derivative Pricing
We have been collaborating for many years with Cluster Technology to develop The Clustertech Parallel Environment (CPE) , a C++ software platform which facilitates the development, deployment and execution of parallel applications. CPE provides optimized domain-specific libraries for Monte Carlo (MC) simulation and for the solution of partial differential equations using the finite difference (FD) method, which greatly reduces the development time of parallel codes. It greatly simplifies the development of parallel derivative pricing products and is production usage in several banks.
We have also developed high speed FPGA-based derivative pricing hardware  which can be used for portfolio analysis and algorithmic trading. Key to this are efficient Gassian random number generators .
