Ian White, Professor of Statistical Methods for Medicine
Ian is a medical statistician with an interest in developing new methodology for design and analysis of clinical trials, meta-analysis and observational studies. He joined the Unit in 2017 after spending 16 years as a programme leader at the Medical Research Council's Biostatistics Unit in Cambridge.
Ian is particularly interested in developing methods for design of non-inferiority and other trials. Other interests in trials are in causal inference, for example to correct for departures from randomised treatment. He has worked for many years in missing data, where he has contributed to the widespread use of multiple imputation and is now developing extensions for missing-not-at-random data. He is also particularly interested in meta-analysis and network meta-analysis, where he has developed methods for assessing and testing inconsistency. He co-wrote a tutorial on simulation studies. He runs courses on many of these topics and has written a range of Stata software.
