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 Deputy Director of the Centre for Interaction Data Estimation and Research (CIDER), one of the data units funded under the ESRC Census Programme.
