My research interests include web-based access to geographic data (including presentation of spatial data, and dissemination of demographic data); disclosure control issues, especially those associated with migration and commuting data, and the past, present and future of census taking and other demographic information capture in the UK.  I am interested in human populations as part of the environment and flows of people as agents of change, including how migrants change the socio-demographic balance of locations.

I am a co-investigator and part of the senior team for CeLSIUS the Centre for Longitudinal Study Information and User Support, which faciliates access to and provides expert support for the ONS Longitudinal Study.

I am a member of the Methodological Assurance Review Panel which reports to the National Statistician providing assurance on the methods being used in the 2021 Census, and reviewing evidence as to the feasibility of fully or partly replacing the census with data based on administrative sources in advance of a possible 2031 Census.
