She has a long-term interest in the communication of expert knowledge – particularly scientific and medical knowledge – across cultural boundaries and to non-expert audiences. Funded by the Wellcome Trust, Roberta has spent the last decade studying the impacts of immigration and ethnicity on postwar British health, medical research and practice. She also convenes the trans-sector and trans-disciplinary IDEA Collaboration (www.go.warwick.ac.uk/IDEACollab) for improving the delivery of ethnically appropriate research, practice and policies in healthcare.
