Teaching interests

Currently I am involved in teaching first year Probability and Applications.   i also tend to find myself teaching non-maths students introductory statistical methods (from Computing, Biomedical Sciences, Environmental Sciences).    A lot of my work at the moment concerns employability and I have been managing a final year work based learning module.

In 2012 I was awarded a National Teaching Fellowship.   I have taught at the African Institute of Mathematical Sciences and have taught from 2007 to 2015 at the University of Bologna.

Staff serving as external examiners

I am external examiner for various Statistics material at Nottingham Trent University and for Maths and Statistics at the University of West Scotland.


I have served as external examiner for an MSc thesis and PhD thesis at Glasgow University.

Research interests

I am interested in generalised linear mixed models (GLMM), particulary for multivariate responses. These models could be considered as a vector of GLMs with the the assumption that there is an underlying multivariate normal random effect. There are a number of ways of approaching these models, I have tended to focus on Bayesian approaches, and have tended to use MCMC. There seem to be two routes to the multivariate normal distribution, one involves a Wishart prior for the multivariate random effects the alternative is to envisage a latent structure with a smaller number of latent variables and a matrix of loading variables which effect a transformation of the latent variables into the higher dimensionality of the response variables. Most of my recent effort has gone into these latent structure models with a view to superimposing a discrete mixing structure, in particular this seems to yield a good method for unsupervised classfication of multivariate count data. However, there seem to be many possibilities to use latent variables with application specific structures, such as having Conditionally Autoregressive Priors, or temporally correlated sets of latent variables or even to allow for spatial structuring.
