The exploratory phase of Vertigo in the City project was enabled by a Wellcome Trust small grant in the Medical Humanities, led by Dr Deriu in collaboration with Dr Josephine Kane (now at Royal College of Art, London). It consisted of a series of meetings, field trips and other activities conducted by a multi-disciplinary team of researchers comprising also Professor John Golding (Department of Psychology, University of Westminster) and Professor Brendan Walker (formerly based at the University of Nottingham, now at Middlesex University, London). This scoping mission culminated in a symposium and workshop held at the University of Westminster’s Faculty of Architecture and The Built Environment (now School of Architecture and Cities) on 29-30 May 2015. It was the first event that brought together scholars and practitioners from the sciences, arts and humanities to discuss how vertigo is variously analysed, treated, conceptualised and represented in relation to cities.
