The research of Erika Hughes and Matt Smith has a shared focus on the transformative effects of applied theatre practices. It has produced new modes and opportunities for engagement, participation and learning for individuals and institutions in the UK and internationally. New audiences, including underserved communities and vulnerable groups, have been attracted and involved through collaborative community engagement projects which have led to changed museum and festival practices and new approaches to community outreach. International initiatives have supported military veterans in the UK and US with mental wellbeing and better public understanding through theatricalized storytelling. Most recently, their work has been instrumental in reaching and educating communities in Kenya on urgent health issues, supporting the understanding of children’s experiences of lung problems and air pollution, and helping to prevent the spread and transmission of Covid-19.
