About Us

The MACH project is collaboration between the London School of Hygiene & Tropical Medicine and the EPPI-Centre at the Institute of Education, University of London.

The research team brings together a broad range of in-depth expertise in meta-analysis and evidence synthesis. We have published two books on systematic review methods covering narrative and meta-analytic methods, contributed to guidance including ESRC guidance on narrative synthesis and will contribute to the forthcoming Cochrane Handbook chapter on complex interventions,  as well as publishing many methodological papers on systematic review methods. We have extensive collective experience having conducted nearly 100 systematic reviews between us, across a wide range of different disciplines – this includes reviews of qualitative research, of intervention studies and observational aetiological studies, using both meta-analytic and narrative methods. The topic areas include education, housing, transport, public health, employment, psychology, health technology assessment, and animal research, among others, and include Cochrane and non-Cochrane reviews. We have published many methodological papers on a wide range of relevant topics including heterogeneity and complexity in systematic reviews and methods of synthesising complex assemblages of evidence. We have organised and contributed to training courses on systematic reviews and meta-analysis, including the EPPI-Centre’s Master of Science (MSc) in Research for Public Policy and Practice; an ESRC-funded course “Training in the quantitative synthesis of intervention research findings in education and social sciences: Meta-analysis in education research” (James Thomas, EPPI-Centre); an ESRC-course “A multilevel approach to meta-analysis for the social sciences” (Alison O’Mara-Eves, EPPI-Centre); meta-analysis training for the National Audit Office (AO); and workshops on systematic reviews of complex interventions at Campbell and Cochrane Colloquia and for NHS organisations (Mark Petticrew, Theo Lorenc). A particular strength of the team is that it combines in-depth methodological expertise with wide experience in a range of different fields, including public health, clinical research, education, psychology, criminology, statistics, and international development.
