Summary

I am responsible for the activities of the Environmetrics research group. We are interested in the spatial variation of soil and related variables, and its implications for sampling, surveying, modelling and doing experiments in the landscape. In 2004 the group was transferred from Silsoe Research Institute to the newly-founded Biomathematics and Bioinformatics Division at Rothamsted.

I graduated in Natural Sciences at Oxford University (1987) with particular interests in soil science and biometrics. I completed my D.Phil. in 1991, on the spatial analysis of satellite imagery, which was supervised by Dr Philip Beckett of the Soil Science Laboratory at Oxford. After holding a University of Wales

Fellowship, I started at Silsoe Research Institute in 1995, eventually moving to the Mathematics group where I established the environmetrics programme on a basis of BBSRC response mode funding, and Government and Industry projects in addition to core funds.
