Laurenz Langer

Senior Research Fellow

Laurenz is a 3ie senior research fellow. He is currently the senior researcher and the evidence synthesis portfolio lead for the Africa Centre for Evidence (ACE) at the University of Johannesburg. Laurenz’s work at ACE involves supporting national government decision-makers to integrate evidence from research syntheses (e.g. evidence maps, systematic reviews, and meta-analyses) in the formulation and design of public policies and programmes. His experience of running a failed sport-for-development programme in the Eastern Cape motivates his passion for using evidence to understand and design public policies that achieve their objectives and improve lives. He strives to support public sector organisations in building effective and sustainable systems for evidence management and use. This includes the institutionalising of policy-relevant evidence maps, responsive evidence services, and co-production approaches. In his role at ACE, Laurenz is building a growing a team of well-respected evidence synthesis experts adapting methods and technologies for synthesis to the contexts of African decision-makers. Laurenz is the lead author of the Science of Using Science report, a systematic review of what works to enhance evidence use and has worked on over 50 evidence syntheses including reviews published by the Campbell Collaboration and the Collaboration for Environmental Evidence. He holds a PhD from the University College London and a BA degree in Development Studies from the University of Johannesburg.
