Professor of Statistics and Health Economics

Department of Statistical Science

University College London


I am a Professor of Statistics and Health Economics in the Department of Statistical Science at University College London. I graduated in Statistics and Economics from the University of Florence (Italy). I then completed a PhD programme in Applied Statistics again at the University of Florence, after a period at the Program on the Pharmaceutical Industry at the MIT Sloan School of Management, Cambridge (USA). I then worked as a Research Fellow and then Lecturer in the Department of Statistical Sciences at University College London (UK).

My main interests are in Bayesian statistical modelling for cost effectiveness analysis and decision-making problems in the health systems, hierarchical/multilevel models and causal inference using the decision-theoretic approach.

I lead the Statistics for Health Economic Evaluation research group within the department of Statistical Science. Our activity revolves around the development and application of Bayesian statistical methodology for health economic evaluation, e.g. cost-effectiveness or cost-utility analysis. We work in close collaboration with academics both within UCL and at other institutions and our activities include a series of seminars aimed at statisticians, health economists and clinicians working in economic evaluations. I collaborate with the UK National Institute for Health and Care Excellence (NICE) as a Scientific Advisor on Health Technology Appraisal projects.

I have served as Secretary (2014-2016) and then Programme Chair (2016-2018) in the Section on Biostatistics and Pharmaceutical Statistics of the International Society for Bayesian Analysis. I have served as an Associate Editor for the Journal of the Royal Statistical Society (Series A) for the period 2015-2021 and have been a member of the Editorial Board of Significance, the magazine of both the Royal Statistical Society and the American Statistical Association in the period 2012-2021. I also am a member of the Scientific Committee of the Bayes Workshop and a member of the technical sub-group tasked by the NHS Medical Director to review the statistical and methodological aspects related to the use of the Summary Hospital-level Mortality Indicator. I have been the 18th Armitage Lecturer in November 2021 (a full video of the talk is here).

I am currently the Head of the UCL Department of Statistical Science (on a 5 years term, from September 2021).

My personal view of the world is that statisticians should be in charge of everything. And, come to think about it, Bayesian statisticians should be in charge of all statisticians.

And brexit sucks. brexit sucks
