In her keynote address for the Posthuman Mimesis conference, part of the ERC-funded HOM project, Katherine Hayles relies on her double training in biology and literary theory to promote a mimetic turn in posthuman studies. With roots in Greek classical drama and development in literary theory, mimesis is often regarded as primarily a discursive technique. Recently, however, Hayles argues that its applications in embodied practices have undergone exponential expansion in an unexpected domain: microbial resistance to viruses.
