Biography and research interests

I am a Reader in Social Statistics and Co-Director of the Centre for Multilevel Modelling (CMM) at the School of Education, University of Bristol, UK.

My methodological interests are in the development, application and dissemination of multilevel and related models to analyse educational and other data. My substantive interests focus on design, analysis, and communication issues surrounding school performance measures and league tables, especially the use of value-added models for estimating school effects on student achievement for accountability and choice purposes.

I was awarded the Frances Wood Medal in the Royal Statistical Society's 2017 honours for my contributions to Social Statistics over the past 10 years, especially my school league table research.

I am currently principal investigator on an ESRC standard grant on new school league table research and am a co-investigator on an MRC grant and on a Swedish Research Council grant. Previously, I held an ESRC Future Research Leaders grant and have been a co-investigator on four other substantial ESRC grants.

My research has been published in various international journals, including: Journal of the Royal Statistical Society, Series A; Journal of Educational and Behavioral Statistics; Journal of Educational Measurement; and Journal of Statistical Software.

I am an Associate Editor of the Journal of the Royal Statistical Society, Series A.

I have taught over 50 multilevel modelling short courses across UK, Europe, Australia and US.

Research grants

I have been grant funded 40% of my time over the ten year period 2010/11 through 2019/20. My grants as Principal Investigator sum to £650,000 while my grants as Co-Investigator sum to over £5 million.

Teaching

My teaching is distinctive in that I deliver training and capacity building in introductory through to advanced quantitative methods. I do this for both post-graduate students and researchers (academic and non-academic) and I do this across the social, behavioural and medical sciences (nationally and internationally).

Current teaching

At masters level, I am a Pathway leader for the MSc Education (Open Pathway). The pathway takes around 120 students per year. I am Unit Director on Multivariate Statistical Methods in Education teaching 30 students per year and Unit Tutor on Statistics in Education teaching 150 students per year.

At EdD level, I supervise one EdD Hong Kong student.

At PhD level, I supervise seven PhD students. Five of these are funded by ESRC scholarships. All these students apply multilevel modelling to address important substantive research questions in the social sciences.

At researcher level, I run two three-day multilevel modelling courses per year for external academic researchers and PhD students. These courses are fee-paying.

I also maintain the our popular LEMMA multilevel modelling online course and have contributed an extensive set of training materials to this resource.

Past teaching

At Undergraduate level, I have taught sessions on Year 1 Convincing Stories and I contributed to the design of Year 2 Educational Statistics.

At Masters level, I was Unit Tutor on MSc Mathematics and Programming Skills, teaching one one-third of this unit. I have also taught sessions on various other masters units. I have supervised masters dissertations and have been a personal tutor at this level.

At EdD-level I have taught sessions on various units.

At PhD-level, I delivered four two-day short courses per year for seven years on various topics in advanced quantitative methods as part of the ESRC SWDTP Advanced Quantitative Methods Pathway. I have also seen five PhD students to completion, four of who were funded by ESRC scholarships. I have been an external PhD examiner for students in Australia, Canada, and UK.

At researcher level, I have taught over 50 multilevel modelling short courses across UK, Europe, Australia and US, including. These include courses for the Eurofound European Agency in Dublin, the Organisation for Economic Cooperation and Development in Paris, and the Royal College of Surgeons in Dublin.

Professional activities

I play an active role in the Royal Statistical Society. I am currently an Associate Editor of the Journal of the Royal Statistical Society, Series A. Since 2008, I have taught (with Professor Harvey Goldstein) an annual two-day course on multilevel modelling for the society's short-course programme. Previously, I sat on the Social Statistics Section committee and the Professional Development Centre committee. I have published in the society's Series A (Statistics in Society) journal and Significance magazine and have peer reviewed for Series A and Series C. I have presented regularly at the society's annual conference and at various society local group meetings.

I currently sit on two expert groups for the Office for Students. I am co-organiser of the DfE funded NPD User Group annual meetings. Previously I have been on an ESRC commissioning panel and on an expert group for the Sutton Trust.

I have peer-reviewed grants for national and international eight research councils and peer-reviewed articles for 27 journals.

I have worked or advised on a range of government and other external projects. These include: Bulgarian Ministry of Education and Science, Catholic University of Portugal, Colombian Evaluation Institute, Higher Education Academy, Home Office, , National Assessment Agency, ACT testing company, National Institute for Certified Educational Measurements Slovak Republic, Pearson Education, RAND Europe, The Times and Sunday Times Data Analysis Team, Swedish Education Department, Trinidad and Tobago Education Department, World Bank.
