See Dr. Wong's Dimensions profile that includes: publications, grants, datasets, patents and clinical trials
Dr. Wong is a health economist and health services researcher with a diverse portfolio of federally funded research. His work applies big data analytics to address questions in four key areas: 1) understanding economic and policy factors influencing healthcare utilization and costs, 2) examining the economic implications of large-scale health system interventions, 3) assessing the economic burden of chronic disease and 4) developing novel methods applications to improve measurement of health system performance.
Conducting research within VA HSR&D provides an exciting opportunity to put VA’s unique data resources to work for Veterans using state-of-the-art methodological approaches.
The long-term goal of my research is to generate new data-driven insights that helps VA identify more effective ways to deliver care for Veterans.
