David Firth FBA
MA (Cambridge), MSc, DIC, PhD (London)
Professor of Statistics, University of Warwick and the Alan Turing Institute
David Firth came to Warwick in 2003 from Oxford, where he was Professor of Social Statistics. Before that he held academic positions at Imperial College London, at the University of Texas at Austin, and at the University of Southampton. He works on statistical theory, methods and computation, and applications in many disciplines, especially social-science and biostatistical applications.
David is in the management teams of the Leverhulme 'Bridges' Doctoral Scholarships Programme and the Warwick/EPSRC Centre for Research in Statistical Methodology (CRiSM). He also represents the Royal Statistical Society in the Methodology Advisory Committee of the UK's Government Statistical Service. Other activities have included directorship of the Warwick Data Science Institute, co-directorship of the EPSRC Academy for Ph.D Training in Statistics, chairing the Research Section of the Royal Statistical Society, and membership of the ESRC Research Grants Board. David is a former Editor of the Journal of the Royal Statistical Society (Series B, Statistical Methodology), and has served as Associate Editor of several other prominent journals including Biometrika and Biostatistics. In 2008 he was elected a Fellow of the British Academy. In 2012 he was awarded the Guy Medal in Silver.
In 2014 he completed a 3-year term as Head of the Department of Statistics.
Current research topics:
- inference and computation for generalized nonlinear models (with Heather Turner and Ioannis Kosmidis);
- inference and computation for complex random-effects models (with Cristiano Varin);
- models of competition and the analysis of pair-comparison data (with Manuela Cattelan, Cristiano Varin, Heather Turner, David Selby and Ian Hamilton);
- compositional data analysis (with Fiona Sammut and Zeeshan Ali);
- penalized likelihood methods, especially for modelling discrete data (with Ioannis Kosmidis).
