From 2001 to 2011 I had a joint appointment in BioSS and the University of Edinburgh’s School of Mathematics. I retired from the University in 2013.
My main research interest in BioSS was the application of Bayesian methods in agriculture. I argued that Bayesian procedures should replace conventional estimative approaches in order to make systematic use of expert knowledge, particularly in making decisions. I applied these ideas to fertilizer optimization (with Mike Talbot) and seed rate optimization (with Adrian Roberts and Mike Talbot).
With Aletta Nonyane and Rob Kempton, I investigated the construction and properties of sequential designs that are balanced for carry-over effects; such designs are used in neuroimaging and visual-perception experiments. See the DesignSequence Page for more information on the designs and their construction.
With Ayona Chatterjee and Graham Horgan, I developed Bayesian models for dietary data recorded on successive days, particularly components of diet which have very skewed distributions.
With Chris Glasbey, Graham Horgan and Caroline Robinson, I investigated principal component analysis of landmarks from two-dimensional images that have approximate bilateral symmetry (called reversible images). The method was applied to improve the automated segmentation of CT X-ray images of sheep.
