Who are we and what do we do?

We are a research group interested in the application of Bayesian statistical methods to computer experiments. In a computer experiment a computer simulator is used to investigate the response of a physical system to a number of variables. Among the uses of computer experiments are

There are several research groups working this this area, but our group is the only group focussed on the problem of large computer simulators, in which there may be hundreds of relevent simulator input variables and simulator outputs, and in which each run of the simulator might take hours or days to complete. These types of simulator are found in applications such as hydrocarbon reservoir management, oceanography and climate modelling, hydrology and environmental monitoring. We are able to handle the huge computational demands of large simulators because we adopt the Bayes linear approach. Details of this approach may be found on the Bayes Linear homepage.

We collaborate actively with commercial partners. We also have extensive software written as libraries of the statistical computing environment R, which are available for use by academics and not-for-profit organisations. Please contact Jonathan Rougier for more details.
