This week Mark interviews Yamni Nigam, Professor of Biomedical Sciences, and Clare Lehane, Impact Support Officer, at Swansea University, about how Yamni got her research on maggot therapy for wounds featured in four episodes of the popular UK soap Casualty, watched by 4.5 million people every week. They have commissioned a polling company to do a before and after evaluation of the impact the episodes have on people’s perceptions of maggot therapy. Yamni’s story shows how curiosity-driven​ research can lead to impact, and how applying that same curiosity to impact can lead to powerful evidence of benefits to the people she has sought to help.​
