Qualifications

  • Bachelor of Arts, University of Oxford

Research interests

  • Randomised Controlled Trials (RCTs)

    Mark has been involved with a plethora of trials of various designs in a broad range of fields. He makes considered, significant contributions to funding applications, trial design, analysis, presentation and interpretation. To date, he has published on 39 randomised trials (protocol and/or results paper). He is involved with methodological research into cluster randomised trials as well as sample size calculations and the anticipated width of 95% confidence intervals.

  • Ready interpretation of log-scale ouput

    Ready interpretation of log-scale ouput such as SD(ln Y), Bias(ln estimator). Symmetric percentage differences such as 100(A – B)/0.5(A + B)% or 100(lnA – lnB)%, Bland-Altman plots, and the summarising, modelling and plotting of lognormal data.

  • Meta analysis

    Mark has been involved with a variety of meta-analyses. He has found a novel way to interpret the heterogeneity parameter, tau, in random-effects meta-analysis of various ratios (e.g. odds ratio, ratio of means etc). He advocates for the reporting of tau (or exp(tau) for ratio measures) rather than tau^2 as it makes appreciating heterogeneity easier.
