Dr Lena Ciric and members of UCL's Healthy Infrastructure Research Group (HIRG) join us to talk about tackling the spread of microbes in urban environments. We discuss how exactly microbes spread around the built environment (and how we know this), as well as the steps scientists and engineers in HIRG are taking to stop them spreading around urban environments. Thanks to Dr Lena Ciric, Dr Melisa Canales, Like Xu and Asrah Binti Mohamad.
