Erika Mansnerus is a British Academy Postdoctoral Fellow at the University of Cambridge, Centre for Research in the Arts, Social Sciences and Humanities (CRASSH) and LSE Health, London School of Economics and Political Science. Her research focuses on how modelling techniques function at the interface of public health research and policy-making. Prior to her British Academy Postdoctoral Fellowship, she was an ESRC Postdoctoral Fellow at the Centre for Analysis of Risk and Regulation (2009). After finishing her PhD in sociology and philosophy of science, at the University of Helsinki (2006), she came to the UK to work as a postdoctoral researcher in an ESRC/Leverhulme Trust funded »Nature of Evidence: How Well Do ›Facts‹ Travel?« project (led by Prof. Mary Morgan at the Economic History Department, 2006–2008). In this interdisciplinary project, she studied the dissemination of model-based ›facts‹ across different research communities and to national health policies.
