I am an Associate Director of UCL Institute of Education's EPPI-Centre and I specialise in methods for systematic reviews and meta-analysis. Prior to joining the EPPI-Centre in November 2010, I worked for a research consultancy conducting evidence reviews for policy and practice, and at the Oxford University Department of Education conducting quantitative research. My DPhil (completed 2009, Oxford University) focused on meta-analytic methods and the application of meta-analysis to research questions on self-concept and self-esteem.
