## Biography

I received a first class BSc in Mathematical Sciences from the University of Bath in 2003, and a PhD in statistics with applications in environmental epidemiology from the same university in 2007. Following a 6-month temporary lectureship and a 1-year research assistant position, both at the University of Bath, I became a lecturer in statistics at the University of Glasgow in September 2007. I have been at the University of Glasgow ever since, and became a professor in August 2018.

## Research interests

My research interests are in developing spatio-temporal statistical methods for use in epidemiology in a predominantly Bayesian setting, focusing on **disease mapping**, **predicting air pollution concentrations**, and investigating the **effects of air pollution on human health**.

My first research area is in **disease mapping** whose aim is to estimate the spatial pattern in disease risk over a city or country, as well as determining whether there has been any increase or reduction in risk over time. These spatio-temporal risk estimates allow public health officials to address key policy questions, such as: (i) where is disease risk highest and which areas are exhibiting an increasing risk of disease over time; (i) how big are the health inequalities in disease risk between rich and poor communities, and how are they changing over time; and (iii) what are the impacts of covariate factors on disease risk.

My second research area concerns **air pollution**, both how to predict it in space and time, and what impact it has on public health. The first of these requires a high-resolution spatio-temporal prediction model to be developed, which allows air pollution concentrations to be predicted at unmeasured locations. The second of these requires regression models to be built that allow for residual spatio-temporal autocorrelation, which allows both the short-term and long-term health effects to be estimated.
