Peter Challenor is a professor in the statistical sciences group of the Department of Mathematics of the University of Exeter. Before joining Exeter he spent many years working for NERC at the National Oceanography Centre in Southampton.
In order to understand the world we use models. These may be derived from the laws of physics and involve the use of partial differential equations or they may be empirical and based on the analysis of data. Such models are increasingly used in aid in decision making in the real world. Such models are never perfect and this needs to be taken into account when they are used in decision making. Professor Peter Challenor's research is concerned with the development of methods to quantify the uncertainty in such circumstances. Applications include models of the environment, climate, engineering and healthcare.
