Andreia Santos BSc MSC PhD

Assistant Professor in Health Economics


I am an economist trained in Brazil and the United Kingdom. I have joined the Department of Global Health and Development in 2013 after having spent several years as a student and staff at the Department of Health Services Research and Policy. In 2007, I obtained a PhD from the London School of Hygiene and Tropical Medicine with a thesis focusing on a mixed model (using insights from psychology and economic theory) to predict choices for sanitation in Salvador, Brazil. I am also a researcher and collaborator for the Institute of Community Health of the Federal University of Bahia, the University of Pernambuco and the Alfredo da Matta Foundation, all in Brazil.




I am a module organiser for GHM101 - Economics of Global Health Policy, and a seminar leader for the Economic Analysis for Health Policy, in-house module.


Most of my research concerns the economics of infectious diseases (costing and cost-effectiveness analyses of interventions) in Brazil, the United Kingdom and in Africa. Since my thesis, I have developed the interest in behaviour economics models that combine economic and psychology theories, and econometrics and statistical techniques to understand the cognitive processes that individuals use to judge future events (e.g. risk of diseases) and make choices.  

Currently, I am part of the Merck for Mothers core research team, leading the efficiency, costing, cost-effectiveness and behaviour economic evaluation studies for the provision of maternal health care services in selected countries. I am also part of the randomised controlled trial team that investigates the effectiveness and cost-effectiveness of interventions for the control of malaria in Tanzania. I am responsible for the cost-effectiveness and behavioural economic components of this study. Other studies involve the costing and cost-effectiveness analysis of HIV/AIDS and tuberculosis interventions, and Chlamydia, syphilis and HIV/AIDS point-of-care tests in Brazil and the United Kingdom.

I am a member of the MSc Ethics Committee, Malaria Centre and HESA.
