Karla Hemming, Senior Editor

Karla is a Professor of Biostatistics at the Institute of Applied Health Research, University of Birmingham, UK. Karla’s research interests include how to design cluster and stepped-wedge trials so as to maximise their statistical efficiency and minimise their risk of bias; how to model time and treatment effect heterogeneity in longitudinal cluster trials; and the ethical issues surrounding these pragmatic trial designs, such as ethical oversight and consent. Karla has recently led the CONSORT extension for the stepped-wedge cluster randomised trial.
