I am Professor of Statistics at the School of Mathematics, Cardiff University. I hold the position of Deputy Head in the School of Mathematics and oversee the Statistics Research Group. I serve as Cardiff's Turing University Network Lead and act as the Academic Lead for Welsh Crucible. My CV is available here.
My research interests are inspired by problems of statistics or data science, and I use ideas from linear algebra and optimisation theory to solve them. At the moment I am particularly interested in the structured low-rank approximation problem, which is the problem of finding a low-rank approximation of a matrix with structure. This has led to new methods and approaches for time-series analysis, for example.
I have also worked in mathematics higher education pedagogy, having worked on diagnostic testing, mathematics support services, the National Student Survey and Teaching Excellence Framework.
I have collaborated extensively with industry, in particular the Office for National Statistics and the NHS, with a number of publications based on our joint work.
