Polly Hudson is a research fellow at The Alan Turing Institute and project lead for the Colouring Cities Research Programme. She is also a senior research fellow at the Centre for Advanced Spatial Analysis, UCL where she developed the Colouring Cities concept as part of her PhD. Polly trained as an architectural historian and cabinet maker, working initially in historic building restoration, slide library design and community planning. In 1991 she directed and designed the Building of Bath Museum and in 1996 set up The Building Exploratory charitable trust in London as a prototype for free, hand-on centres providing joined-up information about the local building stock, built by and for local communities. Here she also began to test designs for public facing GIS platforms able to collate and visualise current, and historical, building attribute data. Since this time she has continued to develop physical and digital educational tools to increase public information about the building stock, and to promote multisector collaboration across the humanities, science, and the arts. Polly has held public appointments at the Department of Culture, Media and Sport, English Heritage, The Royal Institute of British Architects, and The National Lottery.
