About me

​Associate Head of Department (AHoD) for Research and Knowledge Exchange (Department of Health and Social Sciences). I currently lead the Quantitative Health Research module (MSc Public Health and Environmental Health, and Distance Learning MSc Environmental Health). My background is in statistics (MSc Medical Statistics). My PhD, at the University of Plymouth, involved the application of Markov chain Monte Carlo methods to modelling the relationship between maternal age and Down syndrome risk. Postdoctoral research at the International Agency for Research on Cancer used similar models to make projections of cancer incidence and prevalence. I have previously taught statistics and public health to a wide range of students at the Universities of Plymouth and Bristol, and have also worked as an epidemiologist within the Government Statistical Service.

Area of expertise

My research interests broadly involve the application of statistics to health-related data. I have experience of working on randomised controlled trials, cohort studies, case-control studies and cross-sectional surveys, with a particular interest in response rates. Much of my research has been in the field of mental health, from international comparisons of ‘happiness’ and ‘life satisfaction’ to suicide rates amongst military veterans. I also have an interest in sustainability and active travel, and the relationship between physical and mental health. Recent work has studied obesity amongst children, and predictors in childhood of eating disorders in adolescence.
