Since the 1970’s the London School of Hygiene and Tropical Medicine (LSHTM) has been providing health economics research, training and expertise in low and middle income countries, with support from leading funding agencies including: the National Institute for Health Research, UK Research Councils, the Wellcome Trust, government departments, the EU, and the Bill and Melinda Gates Foundation.  LSHTM now employs around 40 health economists, concentrated within our Faculty of Public Health and Policy, with areas of interest spanning countries at all levels of development, and in all subject areas, with specific strengths in work on health systems and services and economic evaluation.  We are also at the forefront of new and emerging areas, including cross-sectoral work on social determinants of health, and techniques for macroeconomic assessment. In all areas, the work of the School is characterised by our commitment to ensure that health economics is underpinned by rigorous methods, is undertaken with strong multidisciplinary links and collaborations, and is relevant to policy.
