Laura Cornelsen

LSHTM profile Googlescholar ORCID  @l_cornelsen

Laura is an Associate Professor in Public Health Economists. She is a public health economist interested in understanding linkages between public health and food systems changes, including the role of food prices as well as health-related food policies in influencing health outcomes. Laura has a MSc degree in Health Economics from University of York and a PhD degree in Economics from Trinity College Dublin. Her PhD work focused on the economic impacts of tobacco control policies in Ireland. After two years of post-doctoral work at the Leverhulme Centre for Integrative Research on Agriculture and Health (LCIRAH) on agri-health economics, Laura was awarded a fellowship in Economics of Health, funded by the UK Medical Research Council (MRC) in 2014. The fellowship work looked at the indirect impact of food taxes and subsidies on food consumption and population health in the UK. In 2017, Laura was awarded a Career Development Award by the UK MRC. Her current work focuses on analysing changes in the dietary patterns in the UK in the past five years using large disaggregated household food and beverage expenditure data and looking at whether food system changes (e.g. industry actions, regulation, policy drivers) have had an impact on what types of foods and beverages people buy and whether these could affect dietary health. Laura also has an interest in Discrete Choice Experiment methods for the prospective analysis of policy effects.

Steve is Professor of Population Health in the Department of Public Health, Environments and Society and Co-Director of the Population Health Innovation Lab (PHI|Lab). He is originally a geographer who moved into epidemiology and population health. He is currently interested in how the built environment affects health and the design and evaluation of the health impacts of environmental interventions. More recently he has begun thinking through whether complex systems theories and methods might offer a way to extend this work and be able to better understand and capture the wide range of potential health effects of social and environmental interventions in transport, food and welfare systems. Current work in which he is involved (alongside many others) includes evaluations of the introduction of taxes and levies on sugar sweetened beverages locally (Jamie’s Italian restaurants) and nationally in (the HM Treasury Sugar Tax), the health effects of transport infrastructure interventions and urban design on active travel,  the role of food banks in the welfare system and the utility of agent—based models for investigations of the potential impacts of population health interventions in the food and transport systems.

Daniel Lewis

Googlescholar ORCID

Daniel was part of the PHI|Lab before taking up his current position as analyst team leader in Data Science & Innovation at the Care Quality Commission. He is interested in the explanatory potential of complexity science, a way of seeing the world that emphasises the interconnectedness of factors that produce health through the adoption of a ‘systems’ perspective. An emerging interest in ‘urban health’ and the health of city dwellers particularly lends itself to a complexity focus. Cities increasingly concentrate both opportunity and inequality, trends in the health and wellbeing of city dwellers cannot be fully explained as the linear combination of independent causal factors, but instead must be understood as being determined by a web of networked sub-systems acting together to produce population health.
