Current Research Interests:

Application of Geometry to Theoretical Statistics:

I am currently working on using geometric ideas, for example differential or convex geometry in Statistics, a good summary of this work can be found in the CUP volume with Mark Salmon [10]. Recently I have been working on using geometric methods to understand mixture models, [6]  gives a general introduction to the idea of a local mixture model which is developed in  [2, 4]. Also some considerations of global geometric issues in statistics can be found in [1, 8].

Applied Stochastic Modelling:

I have worked on a broad range of applied projects across many subject areas; these include  Material Science  [5, 14, 19],  Linguistics [13] , Applied Mathematics [20], Physics [9] and Medical Statistics [3, 15, 17, 18].
