Biography
I joined the University of Southampton in January 2004 after completing my Ph.D. degree in the Department of Geography at the University of Colorado at Boulder in the United States.
Research Interests
My main research interests are migration analysis and estimation and population modelling. Much of this research involves estimating flows in the context of inadequate, inconsistent or missing data. Since coming to Southampton in 2004, I have worked on several projects, including the estimation of international migration flows between countries in the European Union, the projection of age-specific interregional migration in Italy and the estimation of detailed flows by combining census, survey and registration migration data in England and Wales. In February 2009, I started a project on developing dynamic population models for the UK, as part of the ESRC Centre for Population Change.
Work in progress
MIMOSA (MIgration MOdelling for Statistical Analyses), January 2007-December 2009. MIMOSA is a three-year project funded by Eurostat to support the development and application of statistical modeling techniques for the estimation of missing data on migration flows and foreign population stocks. The project is being coordinated by the Netherlands Interdisciplinary Demographic Institute (NIDI) and involves experts on migration from several academic and research institutions. My role has been to develop the framework and model for estimating international migration flows between countries in the European Union, accounting for the many differences in definitions, quality, and sources of available migration data, and to estimate the missing data. The results represent the first time series of harmonized and complete estimates of migration flows between countries in the European Union.
Combining Migration Data in England and Wales, February 2008-July 2009. I am the Principal Investigator on this ESRC-funded project and am working with Prof. Peter W.F. Smith (CO-PI) and Corrado Giulietti (Research Fellow) to develop a methodology for combining registration, census and survey data to produce ‘more detailed’ migration flows over time. Applications include flows by ethnicity, economic activity and education at regional, county and area group levels. Estimating these flows should contribute to a better understanding of population redistribution occurring among different population groups in relation to areas with, for example, high unemployment, high costs of living or high immigrant concentrations.
Developing a Dynamic Population Model for the United Kingdom, February 2009-January 2014. This project is part of the ESRC Centre for Population Change led by Southampton and in partnership with a consortium of Scottish researchers, the Office for National Statistics and the General Register for Scotland. This project includes myself as team leader, Guy Abel (Postdoctoral Research Fellow), Jon Forster (Maths), Peter W.F. Smith (Social Statistics), Jane Falkingham (Demography) and Gabi Durrant (Social Statistics). Our aim is to develop a general and flexible platform for modelling and analysing population change over time. The approach will be applied to applications at various spatial scales and for specific population groups so that we may test theories of demographic change.
Integrated Modelling of European Migration (IMEM), October 2009-September 2011. This project is funded by NORFACE (New Opportunities for Research Funding Agency Co-operation in Europe) and involves myself as Principal Investigator, Jonathan J. Forster, Peter W.F. Smith, Jakub Bijak, Rob van der Erf (Netherlands Interdisciplinary Demographic Institute) and Nico Keilman (University of Oslo). Our aim in this two-year project is to develop a Bayesian model that brings together empirical data and expert judgements on the limitations of the various data sources, including inconsistencies in availability, definitions and quality, to estimate a consistent set of migration flows between countries in Europe with measures of uncertainty.
