I am an Infectious Disease Epidemiologist at the University of Bristol. My research focusses on the epidemiology and control of sexually transmitted infections. I have particular expertise in genital herpes which is caused by infection with herpes simplex virus (HSV), but I also work on chlamydia, human papillomavirus (HPV) and HIV, and optimal access to sexual health services.

I use a variety of quantitative methods in my work, including mathematical modelling, systematic reviews, health economics and data analysis. My research uses these methods to quantify the impact and cost-effectiveness of different interventions, to analyse the burden of infection in the population, and to understand how different infections interact epidemiologically and the consequences for interventions.

I produce the World Health Organization global burden of infection and disease estimates for HSV in collaboration with researchers at Bristol, WHO and the University of Washington, Seattle, USA. I am an Expert for the Global Burden of Disease estimates done by the Institute for Health Metrics and Evaluation in Seattle, and also collaborate with USAID. In the UK current and past projects include work for Health Protection Scotland on behalf of the Scottish Government, and work for local sexual health service commissioners. I am a member of the National Institute for Health Research (NIHR) Health Protection Research Unit in Evaluation of Interventions at Bristol.
