Bob Erens

Honorary Associate Professor

15-17 Tavistock Place
United Kingdom

I have over 35 years experience of applied health and social research and policy evaluation, with a particular focus on survey and evaluation methods. From 2010-2021, I was Deputy Director of the Department of Health & Social Care funded Policy Innovation & Evaluation Research Unit (PIRU), a collaboration between LSHTM, LSE and Imperial College. My current recent research focus is on the integration of health and social care services in England.

Before joining LSHTM, I worked at the National Centre for Social Research (NatCen) in the UK, where I was director of the Health Research Group and the Survey Methods Unit. At NatCen, I was involved in a number of challenging and innovative studies, including the National Survey of Sexual Attitudes & Lifestyles, the first survey on the prevalence of gambling in Britain, a survey on the prevalence of elder abuse in England, and a study on the diet of low income households. I previously directed both the Health Survey for England and the National Patient Experience Survey programme.

I am a Fellow of the Academy of Social Sciences.

My research interests are in the rigorous evaluation of policy pilots and other health initiatives in England, with a particular emphasis on the use of surveys within policy evaluation.  

I'm currently involved in evaluations of the Integrated Care and Support Pioneers and a study monitorying public attitudes to the NHS Test & Trace app. 

I maintain a strong interest in survey methodology, and where possible design methodological experiments into the surveys being used in our evaluations.
