Dr. Maria Alva

Dr. Maria L. Alva is a Senior Research Associate within IMPAQ's Health Division. Her work often involves the development of disease models, based on individual patient data, to predict lifetime costs and outcomes. She is experienced in synthesizing information from multiple sources on costs, outcomes, and effectiveness for decision-analytic models. Dr. Alva has a long-standing interest in non-communicable disease, obesity, and behavioral health.

Expertise

Dr. Alva’s technical expertise includes econometric and statistical methods, linear and nonlinear panel data modeling, survival analysis, missing data and imputation, program evaluation (difference-in- differences, matching, and propensity score estimators), cost-effectiveness analyses, contingent valuation, and meta-analysis. Dr. Alva is published in several peer-reviewed journals, including Health Affairs, Health Economics, and Diabetic Medicine.

Clients

Dr. Alva has more than a decade of research experience. She has worked on impact evaluations addressing aspects of chronic disease prevention such as the Medicaid Incentives for Prevention of Chronic Diseases (MIPCD) Evaluation; the Health Care Innovation Awards Evaluation in Community Resource Planning Prevention and Monitoring (HCIA- CRPPM); and the CDC-RTI simulation model to assess the long-term health and economic outcomes of public health interventions to prevent diabetes and its complications. She has also estimated the direct and indirect cost of tobacco use and the ROI of tobacco cessation investment policies. Her international expertise includes Colombia, El Salvador, Peru, Sri Lanka, Italy, Switzerland, and the UK.

Prior Experience

Prior to joining IMPAQ, Dr. Alva was a health economist at RTI International and a research associate at the Health Economics Research Center at the University of Oxford (U.K.), where she focused on economic analyses of the United Kingdom Prospective Diabetes Study—a landmark trial of policies to improve the management of people with type 2 diabetes.

Education

Dr. Alva holds a DPhil. from the University of Oxford (U.K.) in Public Health in 2013 and an MPhil in Economics from the same institution in 2008. She has been an ad hoc referee for Diabetic Medicine Cerebrovascular Diseases, Medical Decision Making, Medicare & Medicaid Research Review, Value in Health, PLOS ONE, and Health Affairs.
