Teaching

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.

Research

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.
