Chair in Health Economics
Email: firstname.lastname@example.orgTelephone: 020 7882 3863
Borislava Mihaylova is a Professor of Health Economics at the Centre for Primary Care and Public Health, Barts and The London School of Medicine and Dentistry, Queen Mary University of London and leads the work of the health economics team at the Centre.
Borislava has wide ranging interests in health economic evaluation and health policy analyses with particular focus on cost-effectiveness analysis alongside clinical trials, evidence synthesis, heterogeneity in cost-effectiveness and statistical and epidemiologic methods in these areas. Her work on effectiveness and cost-effectiveness of statins for cardiovascular disease prevention has been highly influential in informing treatment recommendations for people at different vascular disease risk.
Professor Mihaylova teaches at postgraduate, graduate and undergraduate levels and supervises students in her research areas.
Borislava was appointed to the Chair in Health Economics at the Centre for Primary Care and Public Health, Barts and The London School of Medicine and Dentistry, Queen Mary University of London in January 2018. She also holds a part-time position of Associate Professor and Senior Health Economist at the University of Oxford's Health Economics Research Centre (HERC).
While studying BSc/MSc in Computer Sciences and Financial Technologies at the Technical University of Sofia, Bulgaria (1990-95), Borislava became involved in the development of the National Health Insurance system in Bulgaria. In 1993-9 she worked at the National Centre of Public Health and National Health Insurance Fund, Bulgaria on the design and implementation of case-mix payment methods for hospital care in Bulgaria. After completing her MSc in Health Economics at the University of York, UK (2000), she took a research post at the University of Southampton working on the health economic analyses of NHS Direct, the NHS out-of-hours system at the time, and growth hormone treatment in children and adults. In 2001-5 she completed a DPhil in Health Economics studying the cost-effectiveness of simvastatin in people at different cardiovascular disease risk in the 20,000-large Heart Protection Study guided by Professors Andrew Briggs, Rory Collins, Alastair Gray, Jane Armitage and Sarah Parish and supported by a NHS Training Fellowship. She continued her research work at the University of Oxford becoming University Research Lecturer in 2011 and Associate Professor in 2015.
Prof Mihaylova is a member of the NIHR Programme Grants for Applied Research (PGfAR) subpanel since June 2016.

Professor Mihaylova’s research programme focuses on studying economic aspects of chronic diseases (eg, respiratory health and asthma, mental health, cardiovascular, chronic kidney disease and diabetes) and interventions and comprises studies of the impact of diseases and interventions on morbidity, mortality, health-related quality of life and healthcare costs; development of disease models to evaluate long-term effects of diseases and interventions, cost-effectiveness analyses of healthcare interventions and studies of socio-economic determinants of health. She leads the development of the economic analyses of policies and treatments studied a number of large randomised (SCENE, SHARP, THRIVE, REVEAL and ACST-2) and non-randomised (ULEZ) controlled studies, and in the individual participant data meta-analysis of statin trials (Cholesterol Treatment Collaboration). Her goal is to generate evidence that reliably informs national and international health policy and improves population health.
Professor Mihaylova leads the Health Economics Research Team.
