Research Interests

My methodological interests are in the application and dissemination of multilevel and other latent variable models to analyse educational and social science data. Particular areas of interest include multilevel analysis of non-hierarchical data (e.g., cross-classified models, multiple membership models), longitudinal data analysis (e.g., growth-curve models, latent class growth analysis, growth mixture models), and dyadic data analysis (e.g., actor-partner interdependence model, social relations model).

My substantive interests are in educational research: school performance indicators and their associated publication in league tables; value-added models (VAMs) for measuring school and teacher effects on student achievement; modelling rater effects on test scoring; neighbourhood, school and family effects on child outcomes.

My statistical software interests are in developing runmlwin and runmixregls, Stata commands to fit multilevel models in the MLwiN and the MIXREGLS software from within Stata.


I am a Senior Lecturer in Social Statisics at the Centre for Multilevel Modelling. I joined the centre in 2005, initially working on the ESRC-funded LEMMA 1 grant (2005-2008). I was a co-investigator on the ESRC-funded LEMMA 2 (2008-2011) and e-Stat (2009-2012) grants and am currently a co-investigator on the ESRC-funded LEMMA 3 (2011-2014) and eBooks (2013-2016) grants. I hold an ESRC future research leaders grant (2013-2015).

I hold a status-only Associate Professor position at the Graduate Department of Applied Psychology and Human Development, University of Toronto. Previously, I have held research positions at the Centre for Market and Public Organisation in the Department of Economics, University of Bristol and was a visiting researcher at Cornell University, Institute of Education, University of York, and VU University Amsterdam.

My ongoing research (with Professor Harvey Goldstein), on the statistical limitations of school league tables , has received considerable attention in the press; including: BBC Radio 4, Financial Times, The Telegraph and The Times Educational Supplement.

I lead three units on the advanced quantitative methods pathway of the ESRC South West Doctoral Training Centre (SWDTC). I often teach short courses on multilevel modelling to academic and other researchers: Belfast, Bristol, Brussels, Cincinnati, Dublin (Centre for Longitudinal Studies in Ireland), Dublin (Royal College of Surgeons, Ireland), Dublin (University College Dublin), Essex, Giessen, Oxford, London (Royal Statistical Society), Paris (Organisation for Economic Cooperation and Development), Tuebingen, and Zurich. I author an extensive set of multilevel modelling training materials for the LEMMA multilevel modelling online course. I second supervise three PhD students. I am a Fellow of the Higher Education Academy.

I have worked or advised on a range of government and other external projects: Catholic University of Portugal, Colombian Evaluation Institute, Higher Education Academy, King’s College London (MRC), National Center for Educational Achievement (NCEA) / ACT testing company, National Assessment Agency, Pearson Education, Rand Europe, The Times and Sunday Times Data Analysis Team, University of Birmingham (DoH), University of Oxford (Ofqual).

I sit on the Royal Statistical Society's Professional Development Centre and Social Statistics Section committees and I co-run the DfE funded PLUG series of workshops.
