In this episode Sophie talks to Dr Rachel Hann who completed her PhD in 2010 from the University of Leeds in theatre and performance. The title of her PhD was 'Computer-based 3D visualization for theatre research: towards an understanding of unrealized utopian theatre architecture from the 1920s and 1930s'. Rachel talks about the importance of supportive, critical supervisors who motivated her to push her research forward. She refers to the influence of the principles of The London Charter for the Computer-based Visualisation of Cultural Heritage used by archeologists on her own methodologies and reflects on the importance of iterative approaches to research, and the need for a clear sense of intention.
