Enrique Bernal-Delgado M.D., Ph.D. is also a Master in Public Health and Master in Health Economics. In 2003, he founded the Data Sciences for Health Services and Policy research group at the Instituto Aragonés de Ciencias de la Salud (IACS) after a period as Visiting Scholar at The Dartmouth Institute (Dartmouth Medical School, NH, USA). Currently, he holds the position of Senior Scientist. His research areas are: a) the comparative study of unwarranted variations in health systems institutional performance (i.e. analysis of equity, utilization, quality and safety, and effectiveness and efficiency); b) the study of the effectiveness of complex real-life health interventions, in particular those delivered to chronic and frail populations; and c) methods and technologies for the reuse of massive real-world data, with an interest in federated research.

Representative research projects:

• AtlasVPM interested in the systematic and comprehensive evaluation of the performance of the Spanish national health system;
• CONCEPT, a project studying the association between care trajectories and health outcomes in four cohorts of patients: acute ischaemic stroke, type II diabetes, congestive heart failure and female breast cancer survivors;
• ICCONIC, a global initiative that is contributing to the comparative analysis of care pathways in high-need high-cost patients;
• In PHIRI and By-COVID, the group has developed the federated infrastructure that has allowed the assessment of indirect effects of the COVID19 pandemic, and the evaluation of the real-life effectiveness of the vaccines, respectively.

Francisco Estupiñán-Romero is a Medical Doctor and specialist in Preventive Medicine and Public Health. He holds two Master's degrees in Public Health and Healthcare Administration and Management. He works as a researcher in the Data Science for Health Services and Policy Research Group at the Health Science Institute in Aragón (IACS). Currently, he is pursuing a PhD in Medicine at the University of Zaragoza (UNIZAR). His research areas are a) the study of unwarranted variations in health systems performance (i.e., the analysis of equity, utilization, quality and safety, and effectiveness and efficiency), including the policy analysis of those health systems; b) the study of real-life effectiveness of complex interventions, particularly those delivered to chronic and fragile populations; and, c) methods and technologies for the reuse of massive real-world data, with interest in federated analyses. He is a collaborating author for the Health System Policy Monitor (HSPM) and the Health System Response Monitor to Spain's COVID-19 pandemic (HSRM) websites by the European Observatory on Health Systems and Policies.

He is a member of the Spanish Atlas of Variations in Medical Practice (AtlasVPM group), the Spanish Research Network (RICAPPS), and the Health Economics Association (AES).
