Juliet's career began as a researcher in central government, before moving to local government. In her role at the Local Government Association, Juliet leads a team that commissions and conducts research projects and analysis to provide evidence and information for the Local Government Association, in its role to speak on behalf of councils, as well as to support local authorities. The team also delivers a programme of work to help authorities make better use of data. Juliet represents the sector in relation to data, including on data burden and the Single Data List; and she leads the LG Inform programme, a data benchmarking service for councils and fire and rescue authorities/services. Juliet is a long-time member of both the Local Area Research and Intelligence Association (LARIA) and the Social Research Association (SRA): she has served on the executive boards of both and is currently a trustee of LARIA. She also sits on the board of GeoPlace, a joint venture between the LGA and Ordnance Survey, that works with councils to produce street and address data.
