Dr Kerry Dwan

Senior Lecturer in Evidence Synthesis

Kerry has a BSc (HONS) in Mathematics from The University of Liverpool, an MSc in Medical Statistics from Lancaster University, and a PhD from The University of Liverpool with her thesis entitled “Outcome reporting bias in meta-analysis”. Kerry then worked at The University of Liverpool as a Trial Statistician and as a Research Associate for the Cochrane Cystic Fibrosis and Genetic Disorders group and the Liverpool Reviews and Implementation Group. In 2015, Kerry moved to Cochrane’s Central Executive Team where she worked as a Statistical Editor. From 2019, she set up and led Cochrane’s Method Support Unit for 3 years. Kerry then worked as a Senior Research Fellow at the Centre for Reviews and Dissemination at The University of York until she joined LSTM Department of Clinical Sciences in May 2023 as a Senior Lecturer in Evidence Synthesis.


The focus of my work and research is to improve the quality of systematic reviews and medical research, specifically in relation to reporting of methods, selective reporting of outcomes and analyses and also the application of complex systematic review methods.
