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 sexual health, HIV epidemiology and global mental health. 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. Work on mental health includes randomised trials to evaluate the effectiveness of lay health-worker delivered counselling interventions for depression, anxiety and alcohol use disorders. Helen has a particular interest in adolescent health including menstrual hygiene management and voluntary medical male circumcision for HIV prevention.
