He has extensive experience in evidence synthesis methodology, particularly in risk-of-bias assessment (riskofbias.info). Luke is passionate about developing new tools to make evidence syntheses faster and more reliable and, despite pronouncing its name oddly, is a staunch advocate of R as a tool for reproducible science.
