Maria Alva is an economist who researches the modeling and evaluation of prevention decisions and the costs and benefits of health interventions. Dr. Alva has particular interests in diabetes, obesity, and population screening. These studies often involve the development and use of disease models, typically based on individual patient data, to predict lifetime costs and outcomes. Dr. Alva’s technical expertise includes econometric methods for panel data, survival analysis, program evaluation (difference-in-differences, matching, and propensity score estimators), and meta-analysis.

Dr. Alva joined RTI in 2013. She previously spent four years at the University of Oxford focusing on the economic analysis of the United Kingdom Prospective Diabetes Study (UKPDS)—a landmark trial of policies to improve the management of people with type 2 diabetes.
