Nicky Best is currently Head of Advanced Biostatistics and Data Analytics at GlaxoSmithKline (GSK), where she leads a team of UK- and US-based statisticians who help drive methodological innovation to enhance the efficiency of clinical trial design, analysis and decision-making strategies. Her work includes embedding the use of prior elicitation, assurance (probability of success) and quantitative decision making strategies into GSK’s drug development process; implementing Bayesian dynamic borrowing methods for formal re-use of historical data in the analysis of new clinical trials and advocating for their use with regulatory agencies; providing training and consultancy on the implementation of the new ICH E9 estimands framework; and providing technical and strategic support for use of digital technologies (e.g. wearables) in clinical trials. She was awarded the RSS/PSI award for Statistical Excellence in the Pharmaceutical Industry in 2015 for her role in implementing prior elicitation and statistical assurance to improve decision making in clinical development. In 2018 she received the RSS Bradford Hill Medal for her work on Bayesian methods in clinical trials, cost-effectiveness, epidemiology and drug development. She currently co-chairs the EFSPI/PSI Historical Data SIG and is a member of the Transcelerate Placebo and Standard of Care Data Sharing workstream.

Prior to joining GSK in 2014, Nicky was an academic statistician at the Medical Research Council Biostatistics Unit in Cambridge and at Imperial College London, where she was professor of Statistics and Epidemiology. She is well known for her work in applied Bayesian statistics in the fields of health and social science, and as a co-developer of the WinBUGS Bayesian software, and has over 100 peer-reviewed publications. She was editor of the RSS Series A journal for several years, and was also a statistical expert witness in some high-profile Government Inquiries in the UK.
