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 adolescent health, sexual health, HIV infection and mental health in low-income settings. She has collaborated on many observational and intervention studies, including recently studies of interventions to improve uptake of HIV testing, linkage-to-care and adherence particularly among young people in southern Africa. 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.
