Helen joined the School in 1997, and is a statistical epidemiologist in the MRC Tropical Epidemiology Group. Prior to coming to the School, Helen studied cancer epidemiology, having obtained her PhD at the Imperial Cancer Research Fund in Oxford, followed by a post-doctoral position at the National Cancer Institute, USA.
Helen teaches epidemiology and statistics on several study units, and co-organises the Advanced Course in Epidemiological Analysis which runs each September, with Liz Allen and Clare Gilham.
Helen's research focuses on HIV epidemiology in developing countries. She has worked on many observational and intervention studies, including the multicentre study of factors associated with the differential spread of HIV in sub-Saharan Africa, and trials of the impact of herpes suppressive therapy on HIV acquisition, educational interventions in young people, and the impact of episodic herpes treatment on HIV infectivity. Helen also has an interest in mental health and was lead statistician on a recent cluster-randomised trial which showed that a lay health worker intervention was effective and cost-effective in reducing morbidity from common mental disorders in Goa, India.
